Catena-Poly[[bis-(pyridine-κN)cadmium]-di-μ(2)-thio-cyanato-κN:S;κS:N].

ABSTRACT: The asymmetric unit of the title compound, [Cd(NCS)(2)(C(5)H(5)N)(2)](n), consists of two crystallographically independent Cd(II) cations, four thio-cyanato anions and four pyridine ligands. The Cd(II) atoms are each coordinated by four N atoms from two pyridine ligands and two thio-cyanato anions, each in a mutually cis orientation, and by two S atoms from two adjacent thio-cyanato anions within a slightly distorted octa-hedral coordination environment. The Cd(II) atoms are μ-1,3-bridged via the thio-cyanato anions into polymeric chains parallel to [001]. The Cd(II)⋯Cd(II) intra-chain separations range between 5.9688 (6) and 6.0195 (6) Å, whereas the shortest Cd(II)⋯Cd(II) inter-chain separations are 7.8272 (7) and 8.6312 (6) Å.

catena-Poly[(E)-4,4'-(ethane-1,2-di-yl)dipyridinium [[bis-(thio-cyanato-κN)ferrate(II)]-di-μ-thio-cyanato-κN:S;κS:N]].

Project description:In the crystal structure of the title compound, {(C(12)H(14)N(2))[Fe(NCS)(4)]}(n), the iron(II) cation is coordinated by four N-bonded and two S-bonded thio-cyanate anions in a distorted octa-hedral coordination mode. The asymmetric unit consists of half an iron(II) cation and half a protonated (E)-4,4'-(ethane-1,2-di-yl)dipyridinium dication, each located on a centre of inversion. In addition, there are two thio-cyanate anions in general positions. The crystal structure consists of Fe-(NCS)(2)-Fe chains in which each iron(II) cation is additionally coordinated by two terminal N-bonded thio-cyanate anions. Non-coordinating dipyridinium dications are present between the thiocyanatoferrate(II) chains and are connected to the anions via N-H⋯N and N-H⋯S hydrogen-bond interactions.

The Schiff base ligand is in the trans conformation.

catena-Poly[silver(I)-bis-[μ-bis-(diphenyl-phosphino)methane-κP:P']-μ-thio-cyanato-κS:S-silver(I)-μ-thio-cyanato-κS:N].

Project description:The title compound, [Ag(NCS)(C(25)H(22)P(2))](n), contains two Ag(+) ions, two thio-cyanate ions and two bis-(diphenyl-phosphino)methane (dppm) ligands in the asymmetric unit. One of the thiocyanate ions bridges the two Ag(+) ions in a μ(2)-mode from its S atom and the two dppm ligands bridge the silver ions in a μ(1),μ(1) mode. The remaining SCN(-) ion bridges the binuclear units via its N and S atoms, generating a one-dimensional polymer propagating in [01]: the resulting AgP(2)SN and AgP(2)S(2) coordination geometries could be described as distorted tetra-hedral.

Crystal structure of catena-poly[[[bis-(pyridine-4-carbo-thio-amide-κN (1))cadmium]-di-μ-thio-cyanato-κ(2) N:S;κ(2) S:N] methanol disolvate].

Project description:The asymmetric unit of the polymeric title compound, {[Cd(NCS)2(C6H6N2S)]·2CH3OH} n , consists of one cadmium(II) cation that is located on a centre of inversion as well as one thio-cyanate anion, one pyridine-4-carbo-thio-amide ligand and one methanol mol-ecule in general positions. The Cd(II) cations are octa-hedrally coordinated by the pyridine N atom of two pyridine-4-carbo-thio-amide ligands and by the S and N atoms of four thio-cyanate anions and are linked into chains along [010] by pairs of anionic ligands. These chains are further linked into layers extending along (201) by inter-molecular N-H⋯O and O-H⋯S hydrogen bonds. One of the amino H atoms of the pyridine-4-carbo-thio-amide ligand is hydrogen-bonded to the O atom of a methanol mol-ecule, and a symmetry-related methanol mol-ecule is the donor group to the S atom of another pyridine-4-carbo-thio-amide ligand whereby each of the pyridine-4-carbo-thio-amide ligands forms two pairs of centrosymmetric N-H⋯S and O-H⋯S hydrogen bonds. The methanol mol-ecules are equally disordered over two orientations.

Adjacent binuclear units are connected by a thio-cyanate anion into a one-dimensional helical chain along [010]. The cyanide anion is disordered, with each site occupied by both C and N atoms in an occupancy ratio of 0.61 (5):0.39 (5). The S atom of the thio-cyanate anion is also disordered over two sites, with occupancy factors of 0.61 (3) and 0.39 (3). There are π-π inter-actions between the pyridyl rings of neighbouring chains [centroid-centroid distance = 3.82 (1) Å].
