The title compound, K2[Cu2(NCS)2(C12H13NO3)2], consists of two K+ cations and (N‐salicylidene‐d ‐valinato)copper(II) and (N‐salicylidene‐l ‐valinato)copper(II) coordination units connected through three‐atom thiocyanate (μ‐NCS) bridges into a centrosymmetric dianion. The CuII atom adopts a square‐pyramidal coordination, with three donor atoms of the tridentate Schiff base and one N atom of the bridging ligand (μ‐NCS) in the basal plane. The axial position is occupied by the thiocyanate S atom of a symmetry‐related ligand at an apical distance of 2.9332 (10) Å. Coulombic interactions between six‐coordinated K+ ions and the heteroatoms of neighbouring dimeric anions leads to the formation of one‐dimensional chains of molecules parallel to [010]. The superposition of the normals of the pyramidal base planes in a direction close to [001] indicates possible π–π interactions between neighbouring units. 相似文献

The title compound, {(C6H14N2)[Ag(NCS)3]}n, is a polymeric silver(I) complex. The AgI atom is hexacoordinated by the S atoms of six thiocyanate anions, with each thiocyanate S atom acting in a bridging mode to link the Ag atoms together. The unique AgI atom lies at a cell origin and has crystallographically imposed symmetry. The diazonia[2.2.2]octane molecule lies about a site with imposed symmetry with the unique N atom on a threefold axis. The S and N atoms of the thiocyanate ligands sit on a mirror plane and a threefold axis, respectively. The crystal structure consists of one‐dimensional chains, which are stabilized by N—H⋯N hydrogen bonds to form a three‐dimensional network. 相似文献

The title complex, [Cu(C11H14BrN2O)(NCS)]n, is an interesting thiocyanate‐bridged polynuclear copper(II) compound, which crystallizes with two independent molecules in the asymmetric unit. Each CuII atom is five‐coordinate in a square‐pyramidal configuration, with one O and two N atoms of one Schiff base ligand and one terminal N atom of a bridging thiocyanate ligand defining the basal plane, and one terminal S atom of another bridging thiocyanate ligand occupying the apical position. The {4‐bromo‐2‐[2‐(dimethylamino)ethyliminomethyl]phenolato}copper(II) units are linked by the bridging thiocyanate ligands, forming polymeric chains running along the a axis. There are weak intermolecular C—H⋯O and C—H⋯S hydrogen bonds between the chains in the crystal structure. 相似文献

The title polymeric compound, catena‐poly[dipotassium [bis[μ‐N‐salicylidene‐β‐alaninato(2−)]‐κ4O,N,O′:O′′;κ4O′′:O,N,O′‐dicopper(II)]‐di‐μ‐isothiocyanato‐κ2N:S;κ2S:N], {K[Cu(NCS)(C10H9NO3)]}n, consists of [isothiocyanato(N‐salicylidene‐β‐alaninato)copper(II)]− anions connected through the two three‐atom thiocyanate (μ‐NCS) and the two anti,anti‐μ‐carboxylate bridges into infinite one‐dimensional polymeric anions, with coulombically interacting K+ counter‐ions with coordination number 7 constrained between the chains. The CuII atoms adopt a distorted tetragonal–bipyramidal coordination, with three donor atoms of the tridentate Schiff base and one N atom of the bridging μ‐NCS ligand in the basal plane. The first axial position is occupied by a thiocyanate S atom of a symmetry‐related μ‐NCS ligand at an apical distance of 2.9770 (8) Å, and the second position is occupied by an O atom of a bridging carboxylate group from an adjacent coordination unit at a distance of 2.639 (2) Å. 相似文献

In the title dinuclear acetate‐bridged complex, [Cu2(C2H3O2)3(NCS)(C10H9N3)2], the two Cu atoms are five‐coordinated, with a basal plane consisting of two N atoms of a di‐2‐pyridylamine (dpyam) ligand and two O atoms of two different acetate ligands. The axial positions of these Cu atoms are coordinated to N and O atoms from thiocyanate and acetate molecules, respectively, leading to a distorted square‐pyramidal geometry with τ values of 0.30 and 0.22. Both CuII ions are linked by an acetate group in the equatorial–equatorial positions and have syn–anti bridging configurations. Hydrogen‐bond interactions between the amine H atom and the coordinated and uncoordinated O atoms of the acetate anions generate an infinite one‐dimensional chain. 相似文献

In the title complex, poly[copper(II)‐di‐μ2‐thiocyanato‐μ2‐1,4‐bis(1,2,4‐triazol‐1‐ylmethyl)benzene], [Cu(NCS)2(C12H12N6)]n, the CuII atom lies on an inversion centre in a tetragonally distorted octahedral environment. Four N atoms from thiocyanate and 1,4‐bis(1,2,4‐triazol‐1‐ylmethyl)benzene (bbtz) ligands fill the equatorial positions, and S atoms from symmetry‐related thiocyanate ligands fill the axial positions. The benzene ring of the bbtz ligand lies about an inversion centre. Single thiocyanate bridges link the CuII atoms into two‐dimensional sheets containing an unprecedented 16‐membered [Cu4(μ‐NCS‐N:S)4] ring. The bbtz ligands further link the two‐dimensional sheets into a three‐dimensional network. 相似文献

The title complex, {[Ni(C2H8N2)3][Na(NCS)3(H2O)]}n, consists of discrete [Ni(en)3]2+ dications (en is ethylenediamine) and polymeric [(H2O)0.5Na(NCS)3(H2O)0.5]n2n? anions. The compound crystallizes in space group Pc1. The NiII atom lies on a threefold axis and has a distorted octahedral coordination geometry. The Na+ cation also lies on a site with imposed crystallographic threefold symmetry and is coordinated by the thiocyanate N atoms (the thiocyanates are in general positions), by one water molecule with crystallographically imposed 32 symmetry and by a second water molecule with crystallographically imposed symmetry. The unique Na atom thus has trigonal–bipyramidal coordination. The O atoms of the water molecules bridge the Na+ cations to form one‐dimensional polymeric chains in the crystal structure. The [Ni(en)3]2+ dications are distributed around and between the chains and are linked to them via N—H?S hydrogen bonds. 相似文献

The asymmetric unit of the title compound, {[Cu(C4O4)(C6H6N2O)2(H2O)2]·2H2O}n, consists of one pyridine‐4‐carboxamide (isonicotinamide or ina) ligand, one‐half of a squarate dianion, a coordinated aqua ligand and a solvent water molecule. Both the CuII and the squarate ions are located on inversion centers. The CuII ions are octahedrally surrounded by four O atoms of two water molecules and two squarate anions, and by two N atoms of the isonicotinamide ligands. The crystal structure contains chains of squarate‐1,3‐bridged CuII ions. These chains are held together by N—H⋯O and O—H⋯O intermolecular hydrogen‐bond interactions, forming an extensive three‐dimensional network. 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

Both molecules are located on crystallographic centres of inversion. In (I), the ZnII atom is five‐coordinated in a trigonal–bipyramidal coordination, with one imine N atom of one Schiff base and two acetate O atoms defining the basal plane, and one O atom and one pyridine N atom of the Schiff base occupying the axial positions, while in (II), the CuII atom is five‐coordinated in a square‐pyramidal coordination, with one O and two N atoms of one Schiff base and one terminal N atom of a bridging thiocyanate ligand defining the basal plane, and one terminal S atom of another bridging thiocyanate ligand occupying the apical position.

Using 2‐aminomethyl‐1H‐benzimidazole as the ligand, a new thiocyanate‐bridged copper(II) complex, namely bis(2‐aminomethyl‐1H‐benzimidazole‐κ2N2,N3)dithiocyanatocopper(II),[Cu(NCS)2(C8H9N3)], has been synthesized and structurally characterized. The Cu atom is five‐coordinated and exhibits a distorted square‐pyramidal geometry. The thiocyanate ions (NCS−) act as either bridging or terminal ligands. The bridging NCS− ligands connect neighboring Cu atoms, constructing chains, while the terminal NCS− ligands form hydrogen bonds with amine H atoms, leading to a complicated network. 相似文献

In the crystal structure of the title compound, [Cu(NCS)(C4H4N2)]n, each Cu atom is coordinated by one N atom of one pyridazine ligand and by one N and two S atoms of three symmetry-related thiocyanate anions within a distorted tetrahedron. Only one N atom of the pyridazine ligand is involved in Cu coordination. The Cu atoms are connected via the thiocyanate anions, forming layers parallel to the ab plane. 相似文献
