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.
