In the title compound, [Co(NCS)(2)(C(19)H(17)N(5)O(2))(2)(CH(3)OH)(2)], the Co(II) atom lies on an inversion center and is coordinated by two isothio-cyanate N atoms, two O atoms of methanol mol-ecules and two pyridine N atoms in a slightly distorted octa-hedral environment. Inter-molecular O-H⋯O and N-H⋯N hydrogen bonds join the complex mol-ecules into layers parallel to the bc plane.

The title compound, [Fe(2)(C(16)H(14)N(2)O(2))(2)(NCS)(2)], is isostructural with the Mn(III)-containing analogue. Each Fe(III) atom is chelated by a tetra-dentate 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate ligand and by the N atom of a thio-cyanate anion, in a square-pyramidal arrangement. The complex mol-ecules form centrosymmetric dimers, with an Fe-O contact of 2.549 (3) Å, ...

In the mononuclear title complex, [Mn(NCS)(2)(C(11)H(11)N(3)O)(4)], the Mn(II) atom, lying on an inversion center, is coordinated by two monodentate thio-cyanate anions and four monodentate 1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one ligands in a distorted octa-hedral geometry. Each complex mol-ecule is linked to four neighboring ones by weak C-H⋯N and C-H⋯S hydrogen bonds, forming a two-dim...

The reported structure is a monoclinic polymorph of the title compound, [Mn(2)(C(16)H(14)N(2)O(2))(2)(NCS)(2)], which has been characterized previously in an ortho-rhom-bic form. Each Mn(III) atom is chelated by a tetra-dentate 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate ligand and by the N atom of a thio-cyanate anion, in a square-pyramidal arrangement. The complexes form centro...

In the crystal structure of the title compound, {[Co(NCS)(2)(C(6)H(4)N(2))(4)]·2C(4)H(8)O(2)}, the Co(II) cations are octa-hedrally coordinated by two terminal N-bonded thio-cyanate anions and four N-bonded 3-cyano-pyridine ligands. The asymmetric unit consists of one Co(II) cation, which is located on a special position with site symmetry 2/m, one thio-cyanate anion and one dioxane mol-ecule, ...

In the title salt, [Hg(NCS)(CH4N2S)3]Cl, the Hg(2+) ion is coordinated in a severely distorted tetra-hedral manner by three thio-urea groups and one thio-cyanate anion through their S atoms. The S-Hg-S angles vary widely from 87.39 (5) to 128.02 (4)°. Weak intra-molecular N-H⋯S hydrogen bonds are observed, which form S(6) ring motifs. In the crystal, the ions are linked by N-H⋯N and weak N-H⋯Cl...

The N-heterocyclic ligand in the title compound, [Cu(NCS)(C(15)H(13)N(5)S(2))](n), coordinates to the Cu(I) atom through its pyridine N-donor site, and adjacent metal atoms are bridged by the thio-cyanate ion, forming a helical chain along the b axis. The geometry of the metal atom is tetra-hedral owing to a somewhat long intra-molecular Cu-S inter-action of 2.5621 (9) Å.

In the title compound, [Ni(NCS)(2)(CH(3)CN)(2)](n), the Ni(II) cation is coordinated by two N-bonded and two S-bonded thio-cyanate anions, as well as two acetonitrile mol-ecules in an octa-hedral NiN(4)S(2) coordination mode. The asymmetric unit comprises one nickel cation, two thio-cyanate anions and two actonitrile mol-ecules. In the crystal, the Ni(II) cations are connected by bridging thio-...
