The title compound, {[Ag(C6H16N2)](C9H7O2)·2H2O}n, has been synthesized and characterized by elemental analysis and single‐crystal X‐ray diffraction. The Ag atom is coordinated in a linear configuration by two N atoms from two hexane‐1,6‐diamine ligands, giving a zigzag polymeric chain with an [–Ag—N—C—C—C—C—C—C—N–]n backbone running parallel to the c axis. In the crystal packing, adjacent chains interact with the anions via the lattice water molecules, thus forming layers parallel to the bc plane. 相似文献

The title compound, {[Cu(C10H8N2)(H2O)](C8H4O4)0.5·H2O}n, has been synthesized hydrothermally and characterized by single‐crystal X‐ray diffraction. The compound consists of nearly linear one‐dimensional chains of [Cu(4,4′‐bipy)(H2O)]nn+ cations (4,4′‐bipy is 4,4′‐bipyridyl), surrounded by isophthalate anions and free water molecules. Hydrogen‐bonding interactions involving cationic chains, isophthalate anions and free water molecules lead to the formation of a three‐dimensional network structure. 相似文献

In the polymeric title compound, [Cu(im)Cl(phen)]n, where im is the imidazolate anion (C3H3N2) and phen is 1,10‐phenanthroline (C12H8N2), each CuII ion is five‐coordinated by four basal N atoms (two from two different im anions and two from one phen ligand) and one axial Cl atom, in a distorted square‐pyramidal coordination geometry. Moreover, each im anion bridges two identical {CuCl(phen)}+ cations through its two N atoms, resulting in a one‐dimensional zigzag chain along the crystallographic a axis. In addition, pairs of adjacent chains are staggered by π–π interactions, generating a two‐dimensional layer, and neighbouring layers are further linked by two different kinds of C—H⋯Cl interactions, producing a three‐dimensional network. 相似文献

In the title coordination polymer, [Pb(NCS)2(C12H12N2)], the coordination geometry about the PbII atom is a distorted octahedron, composed of two N atoms from bpe ligands [bpe is 1,2‐bis(4‐pyridyl)ethane], two other N atoms from NCS? groups and two neighbouring S atoms through short contacts. The trans‐bpe ligands act as bridges between two PbII centres resulting in the formation of a linear chain. The terminal S atoms of the NCS? ligands make short contacts with the PbII atom of neighbouring chains to form an infinite two‐dimensional polymeric structure. 相似文献

The title compound, {[Ag2(C4H4N2)3](CF3SO3)2·2H2O}n, is a polymeric pyrazine–silver(I) complex. Each AgI ion is three‐coordinated by N atoms of three different pyrazine ligands, forming a T‐shaped coordination configuration. In the crystal structure, uncoordinated water molecules are linked to trifluoromethanesulfonate anions through intermolecular O—H⋯O hydrogen bonds. There are weaker Ag⋯O interactions involving the water and sulfonate O atoms. 相似文献

The title compound, [Cu(NO3)2(C4H4N2)2]n, crystallizes as a linear polymeric compound with one pyrimidine ligand bridging between two CuII atoms and a second pyrimidine ligand coordinated in a monodentate manner. The distorted octahedral geometry around the CuII atom consists of two pyrimidine N atoms at distances of 2.033 (4) and 2.025 (4) Å, and two nitrate O atoms at distances at 1.987 (3) and 1.973 (3) Å. The apical positions are occupied by an N atom of a bridging pyrimidine ligand [2.291 (4) Å] and a nitrate O atom at a long distance of 2.781 (3) Å. The basal plane is almost planar, with trans angles of 176.23 (14) and 165.34 (15)°. 相似文献

The polymeric chains run along the c‐axis direction. N—H...O and O—H...O hydrogen bonds involving the coordinating amine groups, nitrate ions and water molecules, as well as cocrystallized noncoordinating nitrate ions and water molecules, generate a three‐dimensional structure. 相似文献

The title complex, [Mn(C8H4O4)(C10H8N2)(H2O)]n, takes the form of a zigzag chain, with the terephthalate dianion (tp) acting as a tridentate ligand. The MnII center is surrounded by two tp ligands, one water molecule and one 2,2′‐bipyridine (bipy) ligand and exhibits a severely distorted octahedral coordination environment, with cis angles ranging from 57.31 (8) to 123.97 (11)°. The complete solid‐state structure can be described as a three‐dimensional supramolecular framework stabilized by hydrogen‐bonding interactions involving the coordinated water molecule and the carboxy O atoms of the tp ligands, and by π–π stacking interactions involving the bipy rings and the benzene ring of the tp ligand. 相似文献

In title (hydrated) trans‐diaquabis(propane‐1,3‐diamine‐κ2N,N′)copper(II) dithionate, [Cu(C3H10N2)2(H2O)2](S2O6) or [{H2N(CH2)3NH2}2Cu(OH2)2](S2O6), both ions have imposed 2/m symmetry. The `axial' anion components are displaced by a pair of water ligands [Cu—O = 2.439 (3) Å], the shorter Cu—O distance being compensated by the lengthened Cu—N distance [2.0443 (18), cf. 2.0100 (13) and 2.0122 (16) Å]. 相似文献

The title complex, {[Fe(C4H4O4)(H2O)4]}n, is an infinite polymeric compound bridged by the succinate dianion. Two carboxylate groups coordinate in a monodentate manner to the FeII atom, in a trans fashion, with an O—Fe—O bond angle of 175.72 (6)° and Fe—O distances of 2.0886 (14) and 2.1008 (15) Å. One of the uncoordinated carboxylate O atom forms an intramolecular hydrogen bond with a coordinated water molecule. Extensive hydrogen bonding between parallel polymeric complex chains results in a three‐dimensional supramolecular structure. 相似文献

The title complex, [Ag(C7H5O2)(C4H5N3)]n, is a polymer based on a mononuclear silver(I)‐centered fragment. The AgI atom is trigonally coordinated by two N atoms from two 2‐aminopyrimidine ligands and one O atom from one benzoate anion, giving zigzag polymeric chains with an [–Ag—N—C—N–]n backbone running along the a axis. It is proposed that intermolecular hydrogen bonding drives the formation of the chain polymer. 相似文献

In the title compound, [Cu2Cl4(C6H10N8)2]n, the ligand has C2 symmetry, and the Cu and Cl atoms lie on a mirror plane. The coordination polyhedron of the Cu atom is a distorted square pyramid, with the basal positions occupied by two N atoms from two different ligands [Cu—N = 2.0407 (18) Å] and by the two Cl atoms [Cu—Cl = 2.2705 (8) and 2.2499 (9) Å], and the apical position occupied by a Cl atom [Cu—Cl = 2.8154 (9) Å] that belongs to the basal plane of a neighbouring Cu atom. The [CuCl2(C6H10N8)]2 units form infinite chains extending along the a axis via the Cl atoms. Intermolecular C—H⃛Cl contacts [C⃛Cl = 3.484 (2) Å] are also present in the chains. The chains are linked together by intermolecular C—H⃛N interactions [C⃛N = 3.314 (3) Å]. 相似文献

Each dadpm ligand, which has a twofold axis passing through its methylene C atom, bridges two Co atoms to form a spiral polymeric chain. Neighbouring chains connect via hydrogen bonds to form a two‐dimensional network. 相似文献

The title complex, [Ag2(C7H5O2)2(C18H18F2N2)]n, is a dinuclear silver(I) compound with one inversion centre between pairs of Ag atoms and another at the mid‐point of the central C—C bond in the butane‐1,4‐diamine moiety. Each of the smallest repeat units consists of two silver(I) cations, two benzoate anions and one N,N′‐bis(2‐fluorobenzylidene)butane‐1,4‐diamine Schiff base ligand. Each AgI ion is three‐coordinated in a trigonal configuration by two O atoms from two benzoate anions and one N atom from a Schiff base ligand. The di‐μ‐benzoato‐disilver(I) moieties are linked by the bridging Schiff base ligand, giving zigzag polymeric chains with an [–Ag⋯Ag—N—C—C—C—C—N–]n backbone running along the b axis. 相似文献

Two new complexes, [Co(C2N3)2(C8H6N2)2], (I), and [Cu(C2N3)2(C8H6N2)2], (II), are reported. They are essentially isomorphous. Complex (I) displays distorted octahedral geometry, with the Co atom coordinated by four dicyanamide nitrile N atoms [Co—N = 2.098 (3) and 2.104 (3) Å] in the basal plane, along with two monodentate quinoxaline N atoms [Co—N = 2.257 (2) Å] in the apical positions. In complex (II), the Cu atom is surrounded by four dicyanamide nitrile N atoms [Cu—N = 2.003 (3) and 2.005 (3) Å] in the equatorial plane and two monodentate quinoxaline N atoms [Cu—N = 2.479 (3) Å] in the axial sites, to form a distorted tetragonal–bipyramidal geometry. The metal atoms reside on twofold axes of rotation. Neighbouring metal atoms are connected via double dicyanamide bridges to form one‐dimensional infinite chains. Adjacent chains are then linked by π–π stacking interactions of the quinoxaline molecules, resulting in the formation of a three‐dimensional structure. 相似文献

The title compound, {[Ag(C4H6NO4)(C4H5N3)]·H2O}n, was synthesized by the reaction of silver(I) nitrate with 2‐aminopyrimidine and iminodiacetic acid. X‐ray analysis reveals that the crystal structure contains a one‐dimensional ladder‐like AgI coordination polymer and that N—H...O and O—H...O hydrogen bonding results in a three‐dimensional network. The AgI centre is four‐coordinated by three N atoms from three different 2‐aminopyrimidine ligands and one O atom from one iminodiacetate ligand. Comparison of the structural features with previous findings suggests that the existence of a second ligand plays an important role in the construction of such polymer frameworks. 相似文献

Yellow needle‐shaped crystals of the title compound, {[Ag(C30H22N4)][Ag(NO3)2]}n, were obtained by the reaction of AgNO3 and 9,10‐bis(benzimidazol‐1‐ylmethyl)anthracene (L) in a 2:1 ratio. The asymmetric unit consists of two AgI cations, one half L ligand and one nitrate anion. One AgI cation occupies a crystallographic inversion centre and links two N‐atom donors of two distinct L ligands to form an infinite one‐dimensional coordination polymer. The second AgI cation lies on a crystallographic twofold axis and is coordinated by two O‐atom donors of two nitrate anions to form an [Ag(NO3)2]− counter‐ion. The polymeric chains are linked into a supramolecular framework via weak Ag...O [3.124 (5) Å] and Ag...π (2.982 Å) interactions (π is the centroid of an outer anthracene benzene ring). The π interactions contain two short Ag...C contacts [2.727 (6) and 2.765 (6) Å], which can be considered to define Ag–η2‐anthracene bonding interactions. In comparison with a previously reported binuclear AgI complex [Du, Hu, Zhang, Zeng & Bu (2008). CrystEngComm, 10 , 1866–1874], this new one‐dimensional coordination polymer was obtained by changing the metal–ligand ratio during the synthesis. 相似文献

The structure of the title compound, catena‐poly[[bis(1,1,1,5,5,5‐hexafluoropentane‐2,4‐dionato‐κ2O,O′)zinc(III)]‐μ‐4,4′‐bipyridine‐κ2N:N′], [Zn(C5HF6O2)2(C10H8N2)]n, consists of polymeric chains, running in two perpendicular directions, organized as planes normal to the tetragonal axis. The elemental unit of the chains is the zinc(II) coordination polyhedron bisected by a twofold symmetry axis, and thus only half of the unit is independent. The octahedral coordination geometry of the metal centre is composed of two oxygen‐chelating (symmetry‐related) hexafluoroacetylacetonate groups and two translationally related 4,4′‐bipyridine groups, which act as connecting agents in the polymer structure. The stabilization of this architecture of chains and planes is associated with a number of weak C—H⋯O and C—H⋯F hydrogen bonds. 相似文献
