In the title compound, [CuCl2(C9H12N2O)], the CuII atom is coordinated by two Cl− anions and two N atoms of one O‐ethyl 3‐methylpyridine‐2‐carboximidic acid molecule in a slightly distorted square‐planar geometry, with Cu—N distances of 2.0483 (17) and 1.9404 (18) Å, and Cu—Cl distances of 2.2805 (10) and 2.2275 (14) Å. In addition, each CuII atom is connected by one Cl− anion and the CuII atom from a neighbouring molecule, with Cu⋯Cl and Cu⋯Cu distances of 2.9098 (13) and 3.4022 (12) Å, respectively, and, therefore, a centrosymmetric dimer is formed. Adjacent molecular dimers are connected by π–π stacking interactions between pyridine rings to form a zigzag molecular chain. The molecular chains are also enforced by N—H⋯Cl and C—H⋯Cl interactions. 相似文献

In catena‐poly[[(di‐2‐pyridylamine‐κ2N,N′)silver(I)]‐μ‐nicotinato‐κ2N:O], [Ag(C6H4NO2)(C10H9N3)]n, the AgI atom is tetracoordinated by two N atoms from the di‐2‐pyridylamine (BPA) ligand [Ag—N = 2.3785 (18) and 2.3298 (18) Å] and by one N atom and one carboxylate O atom from nicotinate ligands [Ag—N = 2.2827 (15) Å and Ag—O = 2.3636 (14) Å]. Bridging by nicotinate N and O atoms generates a polymeric chain structure, which extends along [100]. The carboxyl O atom not bonded to the Ag atom takes part in an intrachain C—H⋯O hydrogen bond, further stabilizing the chain. Pairs of chains are linked by N—H⋯O hydrogen bonds to generate ribbons. There are no π–π interactions in this complex. In catena‐poly[[(di‐2‐pyridylamine‐κ2N,N′)silver(I)]‐μ‐2,6‐dihydroxybenzoato‐κ2O1:O2], [Ag(C7H5O4)(C10H9N3)]n, the AgI atom has a distorted tetrahedral coordination, with three strong bonds to two pyridine N atoms from the BPA ligand [Ag—N = 2.286 (5) and 2.320 (5) Å] and to one carboxylate O atom from the 2,6‐dihydroxybenzoate ligand [Ag—O = 2.222 (4) Å]; the fourth, weaker, Ag‐atom coordination is to one of the phenol O atoms [Ag⋯O = 2.703 (4) Å] of an adjacent moiety, and this interaction generates a polymeric chain along [100]. Pairs of chains are linked about inversion centers by N—H⋯O hydrogen bonds to form ribbons, within which there are π–π interactions. The ribbons are linked about inversion centers by pairs of C—H⋯O hydrogen bonds and additional π–π interactions between inversion‐related pairs of 2,6‐dihydroxybenzoate ligands to generate a three‐dimensional network. 相似文献

In the title one‐dimensional complex, {[MnIII(C9H10NO2)2]Cl}n, the Schiff base ligand 2‐[(2‐hydroxyethyl)iminomethyl]phenolate (Hsae−) functions as both a bridging and a chelating ligand. The MnIII ion is six‐coordinated by two N and four O atoms from four different Hsae− ligands, yielding a distorted MnO4N2 octahedral environment. Each [MnIII(Hsae)2]+ cationic unit has the Mn atom on an inversion centre and each [MnIII(Hsae)2]+ cation lies about another inversion centre. The chain‐like complex is further extended into a three‐dimensional network structure through Cl⋯H—O hydrogen bonds and C—H⋯π contacts involving the Hsae− rings. 相似文献

In the title compound, [Cu(C8H4O5)(C5H5N)2]n or [Cu(OH‐BDC)(py)2]n (where OH‐H2BDC is 5‐hydroxyisophthalic acid and py is pyridine), the Cu atoms are coordinated by two N atoms from the pyridine ligands and by three O atoms from hydroxyisophthalate ligands in a highly distorted triangular bipyramidal environment, with Cu—O distances in the range 1.941 (4)–2.225 (5) Å and Cu—N distances of 2.014 (6) and 2.046 (6) Å. The [Cu(OH‐BDC)]n two‐dimensional network is built up from interlocking 22‐, 15‐ and eight‐membered rings via sharing of Cu atoms and O—H⋯O hydrogen bonds. Consolidation of the packing structure is achieved by edge‐ or point‐to‐face C—H⋯π interactions and offset or slipped π–π stacking interactions. 相似文献

In the title two‐dimensional coordination polymer, [Mn(1,4‐BDOA)(4,4‐bipy)(H2O)2]n [1,4‐BDOA2− is the p‐phenylenedioxydiacetate dianion (C10H8O6) and 4,4‐bipy is 4,4‐bipyridine (C10H8N2)], each MnII atom displays octahedral coordination by two O atoms of the 1,4‐BDOA2− groups, two N atoms of the 4,4‐bipy ligands and two solvent water molecules. The MnII atom, 4,4‐bipy ligand and 1,4‐BDOA2− group occupy different inversion centres. Adjacent MnII atoms are bridged by 1,4‐BDOA2− groups and 4,4‐bipy ligands, forming a two‐dimensional network with Mn⋯Mn separations of 11.592 (2) and 11.699 (2) Å. Hydrogen bonds from a water O—H group link the layers in the third dimension. 相似文献

The title compound, [Ag(CF3O3S)(C10H9N3)]n, is a chain polymer in which neighbouring monomeric units are related by a glide plane. The silver centre is four‐coordinate; the donor atoms are one trifluoromethanesulfonate O atom and one pyridine N atom from each of two symmetry‐related dipyridylamines, and an additional and unexpected Ag⋯C contact [2.6464 (16) Å] is observed to a pyridine C atom. The chains are reinforced by one classical N—H⋯O and two `weak' C—H⋯O hydrogen bonds. 相似文献

In the title compound, [RuCl2(C2H3N)(C27H31N3)]·0.5CH2Cl2, the RuII ion is six‐coordinated in a distorted octahedral arrangement, with the two Cl atoms located in the apical positions, and the pyridine (py) N atom, the two imino N atoms and the acetonitrile N atom located in the basal plane. The dichloromethane solvent molecule lies on a twofold axis. The two equatorial Ru—Nimino distances are almost equal (mean 2.089 Å) and are substantially longer than the equatorial Ru—Npy bond [1.914 (4) Å]. It is observed that the Nimino—M—Npy bond angle for the five‐membered chelate rings of pyridine‐2,6‐diimine complexes is inversely related to the magnitude of the M—Npy bond. The title structure is stabilized by intra‐ and intermolecular C—H⋯Cl hydrogen bonds. The intermolecular hydrogen bonds form an R66(24) ring and a chain of edge‐fused rings running parallel to the [001] direction. 相似文献

The crystal structure of the title compound, [MnCl(C28H22N2O2)(C2H6O)], has been determined at 173 (2) K in the non‐centrosymmetric space group P212121. The asymmetric unit contains two molecular units. An intermolecular O—H⋯Cl hydrogen bond is formed between the OH group of an ethanol molecule coordinated to the Mn atom and the coordinated Cl− anion, and so polymeric chains of Mn‐containing fragments are formed [O—H⋯Cl = 3.1281 (16) and 3.1282 (15) Å]. The Mn atoms have a pseudo‐octahedral coordination sphere, with the four donor atoms of the Schiff base forming an equatorial plane [Mn—O distances are 1.8740 (13), 1.8717 (13), 1.8749 (13) and 1.8823 (13) Å, and Mn—N distances are 1.9868 (15), 1.9910 (14), 1.9828 (15) and 1.9979 (14) Å]. The axial positions are occupied by an ethanol molecule [Mn—O distances of 2.3069 (15) and 2.3130 (15) Å] and a Cl− ligand [Mn—Cl distances of 2.5732 (6) and 2.5509 (6) Å]. 相似文献

In the crystal structure of the title compound {systematic name: bis[6‐methyl‐1,2,3‐oxathiazin‐4(3H)‐one 2,2‐dioxide(1−)‐κ2N3,O4]bis(3‐methylpyridine)copper(II)}, [Cu(C4H4NO4S)2(C6H7N)2], the CuII centre resides on a centre of symmetry and has an octahedral geometry that is distorted both by the presence of four‐membered chelate rings and because of the Jahn–Teller effect. The equatorial plane is formed by the N atoms of two methylpyridine ligands and by the more basic O atoms of the acesulfamate ligands, while the weakly basic N atoms of these ligands are in elongated axial positions with a misdirected valence. The crystal is stabilized by two intermolecular C—H⋯O interactions involving the methyl and CH groups, and the sulfonyl O atoms of the acesulfamate group. 相似文献

In the title compound, C10H9N2+·C9H5INO4S−·2H2O, the 4,4′‐bipyridine molecule is protonated at one of the pyridine N atoms. These moieties self‐assemble into a supramolecular chain along the a axis through N—H⋯N hydrogen bonds. The quinolinol OH group acts as a donor with respect to a sulfonate O atom [O—H⋯O(sulfonate)] and acts as an acceptor with respect to a C—H group of ferron [C—H⋯O(hydroxy)], forming a supramolecular chain along the b axis. These two types of supramolecular chains (one type made up of bipyridine motifs and the other made up of sulfoxine motifs) interact viaπ–π stacking, generating a three‐dimensional framework. These chains are further crosslinked by C—H⋯O hydrogen bonds and O—H⋯O hydrogen bonds involving water molecules. 相似文献

In the title complex, [Mn(C5H4NO)2(C5H5NO)2]n or [Mn(μ‐3‐PyO)2(3‐PyOH)2]n (3‐PyO− is the pyridin‐3‐olate anion and 3‐PyOH is pyridin‐3‐ol), the MnII atom lies on an inversion centre and has octahedral geometry, defined by two N atoms and two deprotonated exocyclic O atoms of symmetry‐related pyridin‐3‐olate ligands [Mn—N = 2.3559 (14) Å and Mn—O = 2.1703 (11) Å], as well as two N atoms of terminal 3‐PyOH ligands [Mn—N = 2.3482 (13) Å]. The MnII atoms are bridged by the deprotonated pyridin‐3‐olate anion into a layer structure, generating sheets in the (01) plane. These sheets are linked by O—H⋯O hydrogen bonds. There are also π–π and C—H⋯π interactions in the crystal structure. 相似文献

In the title complex, [Ag(NO3)(C14H14N4S4)]n, the AgI atom lies on a twofold axis and shows a distorted tetrahedral coordination, comprised of two N‐atom donors from two thiadiazole groups of separate ligands and two O‐atom donors from one nitrate ligand. Each bis(thioether) ligand also lies on a twofold axis and bridges two adjacent Ag atoms to form an infinite chain along the c axis, with an Ag⋯Ag separation of 11.462 (4) Å. Adjacent one‐dimensional chains are further linked into double‐chain motifs through weak Ag⋯S and π–π stacking interactions. 相似文献

The crystal structure of the title compound, tetrachloro[μ‐1,1,4,7,7‐pentakis(1H‐benzimidazol‐2‐ylmethyl)‐1,4,7‐triazaheptane]dimanganese(II) methanol pentasolvate tetrahydrate, [Mn2Cl4(C44H43N13)]·5CH4O·4H2O, contains an asymmetric dinuclear MnII–DTPB [DTPB is 1,1,4,7,7‐pentakis(1H‐benzimidazol‐2‐ylmethyl)‐1,4,7‐triazaheptane] complex with an intra‐ligand bridging group (–NCH2CH2N–), as well as several solvate molecules (methanol and water). Both MnII cations have similar distorted octahedral coordination geometries. One MnII cation is coordinated by a Cl− anion and five N atoms from the ligand, and the other is coordinated by three Cl− anions and three N atoms of the same ligand. The Mn⋯Mn distance is 7.94 Å. A Cl⋯H—O⋯H—O⋯H—N hydrogen‐bond chain is also observed, connecting the two parts of the complex. 相似文献

The title compound, [Cu(ClO4)(C5H6N2)2(C12H12N2)]ClO4, was prepared by in situ partial ligand substitution between 3‐aminopyridine and 4,4′‐dimethyl‐2,2′‐bipyridine at room temperature. The central copper(II) ion is five‐coordinated by one bidentate 4,4′‐dimethyl‐2,2′‐bipyridine molecule, two monodentate pyridine‐coordinated 3‐aminopyridine molecules and one apical O atom from the perchlorate counter‐ion. Intermolecular N—H⋯O and C—H⋯O hydrogen‐bonding interactions form a hydrogen‐bond‐sustained network. 相似文献

In the title compound, [CuCl2(C11H15N3O2)], the CuII ion is five‐coordinated in a strongly distorted trigonal–bipyramidal arrangement, with the two methyloxime N atoms located in the apical positions, and the pyridine N and the Cl atoms located in the basal plane. The two axial Cu—N distances are almost equal (mean 2.098 Å) and are substantially longer than the equatorial Cu—N bond [1.9757 (15) Å]. It is observed that the N(oxime)—M—N(pyridine) bond angle for five‐membered chelate rings of 2,6‐diacetylpyridine dioxime complexes is inversely related to the magnitude of the M—N(pyridine) bond. The structure is stabilized by intra‐ and intermolecular C—H⋯Cl hydrogen bonds which involve the methyl H atoms, except for one of the two acetylmethyl groups. 相似文献

In the title molecular complex, [Cu4Cl6O(2‐EtTz)4], where 2‐EtTz is 2‐ethyltetrazole (C3H6N4), the central O atom is located on the symmetry site and is tetrahedrally coordinated to four Cu atoms, with Cu—O distances of 1.8966 (4) Å. A very slight distortion of Cu4O from a regular tetrahedron is observed [two Cu—O—Cu angles are 108.76 (3)° and four others are 109.828 (13)°]. Each Cu atom is connected to three others via the Cl atoms, forming a slightly distorted Cl octahedron around the O atom, with O⋯Cl distances of 2.9265 (7) Å for Cl atoms lying on the twofold axis and 2.9441 (13) Å for those in general positions. The Cu atom has a distorted trigonal–bipyramidal environment, with three Cl atoms in the equatorial plane, and with the N atom of the 2‐ethyltetrazole ligand and the μ4‐O atom in axial positions. The Cu atom is displaced out of the equatorial plane by ca 0.91 Å towards the coordinated N atom of the 2‐ethyltetrazole ligand. 相似文献

In the title compound, C23H20N2O2S, the central thienopyridine ring system is essentially planar, the dihedral angle between the planes of the two rings being 0.3 (2)°. The terminal ethyl carboxylate group is twisted by 26.7 (3)° away from the central ring system. A short intramolecular hydrogen bond involving the amino N atom and the carbonyl O atom [N⋯O = 2.806 (4) Å] forms a pseudo‐six‐membered ring. Significant intermolecular C—H⋯N, C—H⋯O and C—H⋯π interactions contribute strongly to the stability of the structure, along with weak π–π‐stacking interactions. 相似文献

In the title neutral coordination polymer, [Cd(C6H3ClNO2)2(H2O)2]n, each CdII ion is coordinated by one N and four O atoms from three 2‐chloronicotinate ligands and by two aqua ligands, defining a distorted monocapped octahedral coordination geometry. Adjacent Cd atoms are linked by the pyridyl N atom and the bidentate carboxylate functional group of a 2‐chloronicotinate ligand, forming a one‐dimensional infinite chain along the b axis. The Cd⋯Cd distance is 8.112 (3) Å. These chains are linked by O—H⋯O and O—H⋯N hydrogen bonds into a three‐dimensional network structure. 相似文献

In the title compounds, trans‐[PtI2(C11H14N2OS)2], (I), and trans‐[PtBr2(C11H14N2OS)2], (II), respectively, intramolecular N—H⋯O (propylamine side) hydrogen bonds in the potentially bidentate thiourea ligands lock the carbonyl O atoms into six‐membered rings, determining the S‐monodentate mode of coordination of these ligands. Intramolecular N—H⋯X (X is I or Br) interactions (benzoylamine side) lead to slight distortions of the PtII coordination spheres from ideal square‐planar geometry. The PtII ion is located on an inversion centre in both structures. 相似文献
