The title one‐dimensional chain nickel(II)–disulfide complex, [Ni(C14H8O4S2)(C5H5N)2(H2O)]n, has each NiII cation coordinated by two N atoms from two pyridine ligands, three carboxylate O atoms from two different dithiodibenzoate ligands and one O atom from a coordinated water molecule, in a distorted octahedral coordination geometry. Each dithiodibenzoate ion links two NiII cations through its carboxylate O atoms, making the structure polymeric. Hydrogen‐bond interactions between two shoulder‐to‐shoulder chains lead to the formation of a ladder‐like structure. 相似文献

The tetradentate N2S2 Schiff base ligand 3,3′‐[2,2′‐(ethylenedioxy)dibenzylidene]bis(S‐methyl dithiocarbazate) (H2L), prepared by the condensation of S‐methyl dithiocarbazate with 1,4‐bis(2‐formylphenyl)‐1,4‐dioxabutane in a 1:2 molar ratio, reacts with nickel acetate to form the title neutral metal complex, [Ni(C20H20N4O2S4)]. The X‐ray structure of the complex shows a distorted square‐planar geometry around the Ni atom. The monomeric units are weakly associated into dimers via a long Ni?S interaction [3.569 (1) Å]. These dimeric units are then linked by C—H?S intermolecular contacts to form a polymeric chain along the a axis. 相似文献

The title compounds, [Ni(S2O3)(C12H8N2)2]·0.92H2O·1.4CH4O and [Ni(S2O3)(C10H8N2)2]·2H2O·0.55CH4O, are monomeric, containing nickel(II) in a distorted octahedral coordination environment provided by the four N atoms of two bidentate bipy or phen groups and one S and one O atom from a chelating thiosulfate anion. The crystals are highly unstable outside their mother liquors and are stabilized in solution by a not fully determined number of water and methanol solvate molecules. The phenanthroline structure includes two independent moieties related by a non‐crystallographic inversion center. The thiosulfate anions display the usual S—O lengthening found when the anion acts in a bidentate mode. 相似文献

The title compound, [Mg(C5H4NOS)2(H2O)2]·C10H8N2O2S2, is a two‐component host–guest material. The 2,2′‐dithiobis(pyridine N‐oxide) molecule has crystallographic twofold symmetry. The metal complex lies on an inversion centre and associates via C—H?S interactions into chains which thread the 2,2′‐dithiobis(pyridine N‐oxide) lattice in perpendicular directions. Hydrogen bonds exist between the water molecules of the diaquamagnesium units and the N—O groups of the host lattice. 相似文献

The title compound, [Ni(C3H10N2)2(H2O)2](C6H6NO3S)2, contains alternating layers of sulfanilate anions and diaquabis(1,3‐propanediamine)nickel(II) cations. The Ni atom lies on an inversion centre and is hexacoordinated by the 1,3‐propanediamine ligands, which function as N,N′‐bidentate ligands, and the water molecules, which are in a trans arrangement. The sulfanilate anions are arranged in layers, with the sulfonate and amine groups directed towards opposite sides of the layer. The structure is stabilized by a network of hydrogen bonding between the O and N atoms of the sulfanilate anions, the water molecules, and the N atoms of the 1,3‐propanediamine ligands. 相似文献

In the title compounds, {2,2′‐[2,2‐dimethyl‐1,3‐propanediylbis(nitrilomethylidyne)]diphenolato‐κ4N,N′,O,O′}nickel(II), [Ni(C19H20N2O2)], and {2,2′‐[2,2‐dimethyl‐1,3‐propanediylbis(nitrilomethylidyne)]diphenolato‐κ4N,N′,O,O′}copper(II), [Cu(C19H20N2O2)], the NiII and CuII atoms are coordinated by two iminic N and two phenolic O atoms of the N,N′‐bis(salicylidene)‐2,2‐dimethyl‐1,3‐propanediaminate (SALPD2?, C17H16N2O22?) ligand. The geometry of the coordination sphere is planar in the case of the NiII complex and distorted towards tetrahedral for the CuII complex. Both complexes have a cis configuration imposed by the chelate ligand. The dihedral angles between the N/Ni/O and N/Cu/O coordination planes are 17.20 (6) and 35.13 (7)°, respectively. 相似文献

The title compound, [Mn(C12H8N2)2(H2O)2](C4H4O4S)·[Mn(C4H4O4S)(C12H8N2)2]·13H2O, contains one dianion of thiodiglycolic acid (tdga2−) and two independent manganese(II) moieties, viz. [Mn(phen)2(H2O)2]2+ and [Mn(tdga)(phen)2], where phen is 1,10‐phenanthroline. The MnII atoms are octahedrally coordinated by four N atoms of two bidentate phen ligands [Mn—N = 2.240 (2)–2.3222 (19) Å] and either two water O atoms or two tdga carboxyl O atoms [Mn—O = 2.1214 (17)–2.1512 (17) Å]. The tdga ligand chelates as an O,O′‐bidentate ligand, forming an eight‐membered ring with one Mn atom. The free tdga2− dianion is hydrogen bonded to an [Mn(phen)2(H2O)2]2+ ion, with O⋯O distances of 2.606 (2) and 2.649 (2) Å. The crystal structure is further stabilized by an extensive network of hydrogen bonds involving 13 water molecules. 相似文献

The title compound, (C7H10N)[Ni(C3S5)2] or (Etpy)[Ni(dmit)2] (where Etpy is the N‐ethylpyridinium cation, C7H10N+, and dmit is the 2‐thioxo‐1,3‐dithiole‐4,5‐dithiolate dianion, C3S52−), crystallizes in the P space group with two molecules in the asymmetric unit. The [Ni(dmit)2]− monoanion has a planar D2h conformation, with the central Ni atom and the four coordinated S atoms forming an NiS4 square plane. The six‐membered ring of the Etpy cation also shows good planarity, as expected. There are two main types of disorder in the two Etpy cations. Several short intermolecular interactions are present, such as S⋯S, Ni⋯S and Ni⋯Ni, which help to form the enhanced three‐dimensional structure of the crystal. 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

In the title complex, trans‐{2,2′‐[cyclohexane‐1,2‐diylbis(nitrilomethylidyne)]diphenolato‐κ4O,N,N′,O′}nickel(II)–chloroform (1/1), [Ni(C20H20N2O2)]·CHCl3, the Ni atom has a square‐planar geometry, slightly tetrahedrally distorted. The Ni—N and Ni—O bonding distances are within the expected ranges for Ni–Schiff base derivatives. The diimine bridge has a gauche conformation with the cyclohexyl ring almost coplanar with the NiN2O2 plane. The complex molecules pack in dimers with an Ni?Ni distance of 3.59 (1) Å and form a three‐dimensional structure displaying a herring‐bone configuration. Channels are occupied by solvent molecules, which are involved in C—H?O hydrogen bonds with the ligand O atoms. 相似文献

Bridging by the two thiocyanato groups in centrosymmetric six‐coordinate bis(thiocyanato)bis(diphenylthiourea)cadmium(II) dihydrate leads tothe formation of eight‐membered [Cd—SCN→Cd—SCN→] rings that are linked at the metal atom to furnish chains running parallel to the a axis, i.e {[Cd(NCS)2(C13H12N2S)2]·2H2O}n. 相似文献

The title structure, [Rh2(C7H5O3)4(C2H6OS)2]·[Rh2(C4H7O2)4(C2H6OS)2]·2C2H6O, contains two discrete neutral Rh–Rh dimers cocrystallized as the ethanol disolvate. Each dimer is situated on an inversion center. The butyrate chain displays disorder in one C‐atom position. In each dimer, the dimethyl sulfoxide ligand (dmso) is bound via S, as expected. The ethanol is a hydrogen‐bond acceptor for one p‐hydroxybenzoate hydroxyl group and acts as a hydrogen‐bond donor to the dmso O atom of a neighboring p‐hydroxybenzoate dirhodium complex. A third hydrogen bond is formed from the other p‐hydroxybenzoate hydroxyl group to the dmso O atom of a butyrate–dirhodium complex. 相似文献
