چکیده
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).

Attempts to prepare the mononuclear [(tpm)Ni(II)L(3)](-1) [tpm = tris-(1H-pyrazol-1-yl)methane and L = thio-cyanate] anion yielded the methanol-solvated salt, [(tpm)(2)Ni(II)][(tpm)Ni(II)(NCS)(3)](2)·2CH(3)OH or [Ni(C(10)H(10)N(6))(2)][Ni(NCS)(3)(C(10)H(10)N(6))](2)·2CH(3)OH. The asymmetric unit consists of half a centrosymmetric bis-[tris-(1H-pyrazol-1-yl)methane]-nickel(II) cation and an octa...

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)...

The title compound, [Cd(NCS)(2)(C(6)H(5)N(5))(2)](n), is a coordination polymer with the Cd(II) centre located on a twofold rotation axis. The Cd(II) centre assumes a distorted octa-hedral geometry. The thio-cyanate anions function as bridging ligands between the Cd(II) centres, leading to a chain-like arrangement expanding along [001].

In the title compound, [Fe(NCS)2(C8H6N4S2)2] n , the Fe(II) cation is coordinated by two terminal N-bonded thio-cyanate anions and four bridging N:N'-bridging dipyrazin-2-yl di-sulfide ligands in an octa-hedral geometry. The Fe(II) cations are connected via bridging 4,4'-di-pyrazine ligands into chains along the b-axis direction. The asymmetric unit consists of one Fe(II) cation located on posi...
