【 摘 要 】

In the crystal structure of the title compound, [Ni(NCS)2(H2O)4]·4C6H8N2, the NiII cations are coordinated by four water ligands and two trans-coordinated terminally N-bonded thio­cyanate anions in a slightly distorted octa­hedral geometry. The asymmetric unit consists of a Ni2+ cation located on a centre of inversion, two water mol­ecules and one thio­cyanate ligand, as well as two uncoordinated 2,5-di­methyl­pyrazine ligands in general positions. In the crystal, discrete complex mol­ecules are linked into a three-dimensional network by O—H⋯N hydrogen bonding between the water H atoms and the 2,5-di­methyl­pyrazine N atoms.
