Poly[tris-[μ(2)-2-(pyrazol-1-yl)pyrazine]hexa-μ(1,3)-thio-cyanato-tricadmium(II)].

ABSTRACT: The asymmetric unit of the title crystal structure, [Cd(3)(NCS)(6)(C(7)H(6)N(4))(2)](n), contains two independent Cd(II) ions, one of which is located on a crystallographic inversion center. Each independent Cd(II) ion is in a slightly distorted octa-hedral coordination environment, but the disortion from ideally octa-hedral is greater in the environment of the Cd(II) ion on a general position. Both thio-cyanate ligands act as bridges connecting independent Cd(II) ions, and the 2-(pyrazol-1-yl)pyrazine ligands chelate one Cd(II) ion in a bidentate mode while the remaining N atom of the pyrazine ring coordinates to a symmetry-related Cd(II) ion, forming a two-dimensional structure parallel to (211).

Project description:In the title compound, [Au(2)Ba(NCS)(4)(C(20)H(24)O(6))](n), the dithio--cyanato-aurate(I) anion adopts a dimeric structure with an Au⋯Au distance of 3.1109 (10) Å; both Au(I) atoms are also bonded to two S atoms. The Ba(II) ion adopts an irregular BaN(3)O(6) geometry, arising from the crown ether and three adjacent thio-cyanate N atoms; the extended structure of the complex can be described as a one-dimensional coordination polymer generated by the Ba⋯N inter-actions (two on the endo side and one on the exo side of the crown ether) running parallel to the b axis, with an anti-parallel arrangement of ribbons in the unit cell.

Poly[bis-(methanol-κO)tris-(μ-pyrimidine-κN:N')tetra-kis(thio-cyanato-κN)dinickel(II)].

Project description:In the crystal structure of the title compound, [Ni(2)(NCS)(4)(C(4)H(4)N(2))(3)(CH(3)OH)(2)](n), each nickel(II) cation is coordinated by three N-bonded pyrimidine ligands, two N-bonded thio-cyanate anions and one O-bonded methanol mol-ecule in a distorted octa-hedral environment. The asymmetric unit consists of one nickel cation, two thio-cyanate anions and one methanol mol-ecule in general positions, as well as one pyrimidine ligand located around a twofold rotation axis. The crystal structure consists of μ-N:N' pyrimidine-bridged zigzag-like nickel thio-cyanate chains; these are further linked by μ-N:N-bridging pyrimidine ligands into layers which are stacked perpendicular to the b axis. The layers are connected via weak O-H⋯S hydrogen bonding.

Project description:In the crystal structure of the title compound, [Cd(NCS)(C(6)H(4)NO(2))(C(2)H(5)OH)](n), the Cd(2+) cation is coordinated by one N and two O atoms of two symmetry-related isonicotinate anions, one ethanol mol-ecule and two μ-1,3-bridging thio-cyanate anions in a distorted octa-hedral N(2)O(3)S geometry. The metal cations are μ-1,3-bridged via thio-cyanate anions into chains that are further connected into layers parallel to the ab plane by bridging isonicotinate anions. The layers are stacked along the c axis. The crystal structure is stabilized by O-H⋯O hydrogen bonds.

Tetra-ethyl-ammonium tris-(thio-cyanato-κN)[tris-(1H-pyrazol-1-yl-κN(2))methane]-nickelate(II).

Project description:The title salt, (C₈H₂₀N)[Ni(NCS)₃(C₁₀H₁₀N₆)], consists of a tetra-ethyl-ammonium cation and an anion comprising an octa-hedral Ni(II) atom surrounded by three N atoms from a tripodal tris-(pyrazol-1-yl)methane ligand, and three thio-cyanate ligands, each bound at the N-atom end. The ligand Ni-N distances range from 2.097 (2) to 2.127 (2) Å for the tripodal ligand and from 2.045 (2) to 2.075 (2) Å for the thio-cyanate ligands. The dihedral angles between the three pyrazole rings are 59.03 (12), 53.09 (10) and 67.90 (10)°.

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.

Poly[μ-4,4'-bipyridine-κN:N'-μ-thio-cyanato-κN:S-copper(I)].

Project description:In the crystal structure of the title compound, [Cu(NCS)(C(10)H(8)N(2))](n), the Cu(I) atom is coordinated by two N atoms from two symmetry-related 4,4'-bipyridine (bipy) ligands and one N and one S atom from two symmetry-related thio-cyanate ligands in a distorted tetra-hedral environment. The thio-cyanate ligands bridge the Cu(I) atoms into a zigzag [CuSCN](n) chain running parallel to the a axis. These chains are further connected through two bipy ligands that bridge the Cu(I) centers to generate a two-dimensional brick-like network. The pyridyl planes of the ligands exhibit a dihedral angle of 37.35 (12)°.
