biostudies-literatureUnknown71(Pt 2)Suckert SIn the crystal structure of the title compound, [Ni(NCS)2(H2O)4]·4C6H8N2, the Ni(II) cations are coordinated by four water ligands and two trans-coordinated terminally N-bonded thio-cyanate anions in a slightly distorted octa-hedral geometry. The asymmetric unit consists of a Ni(2+) cation located on a centre of inversion, two water mol-ecules and one thio-cyanate ligand, as well as two uncoordinated 2,5-di-methyl-pyrazine ligands in general positions. In the crystal, discrete complex mol-ecules are linked into a three-dimensional network by O-H⋯N hydrogen bonding between the water H atoms and the 2,5-di-methyl-pyrazine N atoms.Acta crystallographica.
