In the title compound, [Ru(C10H8N2)2(C12H8N2)][Pt(CN)4], cations and anions alternate along the a axis to afford a one‐dimensional network. The one‐dimensional character arises from the π–π stacking as well as from the electrostatic interactions formed between the phen (1,10‐phenanthroline) and [Pt(CN)4]2− units. Two adjacent one‐dimensional chains form further stacks based on the π–π stacking interactions between the phen moieties, where the interplanar spacing is 3.50 (1) Å. 相似文献

In the crystal structure of the title compound, [Zn(C4H13N3)2]2[Fe(CN)6]·4H2O, the asymmetric unit is formed by a [Zn(dien)2]2+ cation (dien = diethylenetriamine, NH2CH2CH2NHCH2CH2NH2), water molecules and half of the [Fe(CN)6]4? anion which is related by inversion symmetry through the Fe atom. The geometry around the Zn and Fe atoms is distorted octahedral and octahedral, respectively. Intramolecular O—H?O hydrogen bonds involving the water molecules, and intermolecular O—H?N hydrogen bonds involving the water molecules and the anions, result in an infinite chain. Intramolecular O—H?O and N—H?N, and intermolecular O—H?N, N—H?O and N—H?N hydrogen bonds form a three‐dimensional framework. 相似文献

The synthesis and crystal structure of the mononuclear title compound, [Co(C2O4)(C10H8N2)2]·5H2O, is reported. The Co atom is six‐coordinated by two O atoms of a bidentate oxalate group and by four N atoms of two bipyridine ligands. The neutral [Co(C2O4)(C10H8N2)2] entities are connected by π–π stacking interactions of the aromatic systems into a two‐dimensional layer, interconnected through a ladder‐like hydrogen‐bonding pattern of solvate water molecules. 相似文献

In the two isomorphous title compounds, viz. tris[2,2′‐bi(4,5‐dihydro‐1,3‐oxazole)‐κ2N,N′]copper(II) diperchlorate, [Cu(C6H8N2O2)3](ClO4)2, (I), and tris[2,2′‐bi(4,5‐dihydro‐1,3‐oxazole)‐κ2N,N′]nickel(II) diperchlorate, [Ni(C6H8N2O2)3](ClO4)2, (II), the MII ions each have a distorted octahedral coordination geometry formed via six N atoms from three 2,2′‐bioxazoline ligands. For each ligand, the two five‐membered rings are nearly coplanar. It is noteworthy that the Jahn–Teller effect is stronger in (I) than in (II). The three‐dimensional supramolecular structures of (I) and (II) are formed via weak hydrogen‐bonding interactions between O atoms from perchlorate anions and H atoms from 2,2′‐bioxazoline ligands. 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

The title compound, [Co(C10H8N2)3]2[V4O12]·11H2O, is composed of two symmetry‐related cations containing octahedrally coordinated CoII ions, a centrosymmetric [V4O12]4− anion with an eight‐membered ring structure made up of four VO4 tetrahedra, and 11 solvent water molecules. The CoII cations and vanadate anions are isolated and build cation and anion layers, respectively. In addition, the title compound exhibits a three‐dimensional network through intra‐ and intermolecular hydrogen‐bond interactions between water molecules and O atoms of the anions, and the crystal structure is stabilized mainly by hydrogen bonds. 相似文献

The title double salt, [Ni(C2H8N2)3]2(SbS4)(NO3), was crystallized under solvothermal conditions. Hydrogen bonds between the SbS43? anions (at four sites) and the [Ni(en)3]2+ (en = ethylenediamine) cations (at two sites) form a three‐dimensional network. The NO3? anion is disordered over four sites. The cation lies on a twofold rotation axis and the SbS43? anion on a axis. 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

The asymmetric unit of the title compound, [Zn(C7H5O3)2(C10H8N2)], contains one monomeric zinc complex. The Zn atom is coordinated to one 2,2′‐bipyridyl ligand via both N atoms and to two salicylate anions (Hsal−) in a bidentate chelating manner involving carboxylate O‐atom coordination. The complex exhibits a distorted octahedral geometry about the ZnII atom, with the `apical' positions occupied by one of the two N atoms of the bipyridyl ligand and an O atom from one Hsal− ligand; the Zn atom is 0.168 (1) Å out of the `basal' plane. Two intramolecular six‐membered hydrogen‐bonded rings are present, generated from interactions between the carboxyl and hydroxyl groups of the salicylate ligands. The crystal packing is governed by weak C—H⋯O and C—H⋯π interactions. 相似文献

The Cu atom in the title complex {[Cu(C10H8N2)(C12H8N2)(ClO4)2]·H2O}n, has an N4O2 octahedral coordination geometry, the Cu atoms being bridged by the bipyridine and chelated by the phenanthroline heterocycles. Adjacent molecules are linked into a zigzag chain running along the c axis of the monoclinic unit cell. The chains are connected through lattice water molecules to produce a layer structure. 相似文献

In the title compounds, [Pd(C10H6O2)(C10H8N2)], (I), and [Pd(C10H6O2)(C18H12N2)], (II), each PdII atom has a similar distorted cis‐planar four‐coordination geometry involving two O atoms of the 2,3‐naphthalenediolate dianion and two N atoms of the 2,2′‐bipyridine or 2,2′‐biquinoline ligand. The overall structure of (I) is essentially planar, but that of (II) is not, as a result of intramolecular overcrowding leading to bowing of the biquinoline ligand. 相似文献

In the title complex, [Co2(C10H2O8)(C10H8N2)2(H2O)2], the four carboxylate groups are fully deprotonated and coordinate to four CoII cations in a monodentate fashion, forming a one‐dimensional ribbon‐like double‐chain structure, with centrosymmetric [Co2(C10H2O8)(C10H8N2)2(H2O)2] repeating units and a cavity of approximately 6.8 × 6.6 Å. Moreover, a three‐dimensional supramolecular structure is formed by face‐to‐face π–π interactions between the aromatic rings of the 2,2′‐bipyridine moieties of two adjacent chains, and by hydrogen‐bonding interactions between the coordinated aqua O atom and the coordinated carboxyl O atom from different chains. 相似文献

The crystal structure of the title compound, [NiCl(C12H8N2)2(CH4N2S)]2(NO3)Cl·2C2H6O, is formed by [Ni(phen)2(thiourea)Cl]+ cations (phen = 1,10‐phenanthroline), chloride and nitrate counter‐ions, and ethanol solvate molecules. The Ni atom is octahedrally coordinated to two bidentate phen ligands, a monodentate thiourea and a chloride ion. Both the chloride and nitrate anions, which provide charge balance, are located at special positions on a twofold symmetry axis. Hydrogen bonds play a key role in the packing and conformation of the cation and create a three‐dimensional network. 相似文献

The structure of the title compound, [Zn(C12H11N2O2S)2(C10H8N2)], consists of monomeric molecules in which the central ZnN2N′N′′ unit has a distorted tetrahedral geometry, with bond lengths ranging from 2.020 (3) to 2.109 (3) Å. The anionic ligands are potential bidentate donors and thus there are two secondary Zn—N interactions. The shorter of these is 2.317 (3) Å and completes at the Zn atom an irregular five‐coordinated geometry, which can be described as a square pyramid showing 30% distortion towards the trigonal bipyramid; the other Zn—N contact is much longer at 2.549 (3) Å. 相似文献

The title compound, [Cu(Cr2O7)(C10H8N2)2], a new mixed‐metal molecular compound, contains isolated molecular units, each comprised of one CuII atom coordinated to two 2,2′‐bipyridine ligands and also to an oxygen vertex of a dichromate anion. The CuII atom has an approximate trigonal–bipyramidal geometry, which is consistent with previous studies. Both enantiomers of the chiral complex molecule are present and are related by inversion centers. In a reported pyridine analogue, achiral [Cu(Cr2O7)(pyridine)4] chains pack in the non‐centrosymmetric space group Pna21. Differences in the organic ligands influence the chirality and dimensionality of the Cu—Cr2O7 bonding. 相似文献

The title compound, [Pt2III(C5H10NO)2(SO4)2(C10H8N2)2]·4H2O, is the first reported example of a complex in which an amidate‐bridged Pt(bpy) dimer is stabilized in the oxidation level of PtIII (bpy is 2,2′‐bipyridine). The asymmetric unit consists of one half of the formula unit with a twofold axis passing through the center of the dimer. The intradimer PtIII—PtIII bond distance [2.5664 (6) Å] is comparable to those reported for α‐pyridonate‐bridged cis‐diammineplatinum(III) dimers [2.5401 (5)–2.5468 (8) Å; Hollis & Lippard (1983). Inorg. Chem. 22 , 2605–2614], in spite of the close contact between the bpy planes within the dimeric unit. The axial Pt—Osulfate distance is 2.144 (7) Å. 相似文献
