title: Bis(2,3,5,6-tetra-2-pyridyl-pyrazine-κN,N,N)nickel(II) dithio-cyanate dihydrate.
abstract: In the title compound, [Ni(C(24)H(16)N(6))(2)](NCS)(2)·2H(2)O, the central Ni(II) ion is octahedrally coordinated by six N atoms of two tridentate 2,3,5,6-tetra-2-pyridyl-pyrazine ligands (tppz). Two thio-cyanate anions act as counter-ions and two water mol-ecules act as solvation agents. O-H⋯N hydrogen bonds are observed in the crystral structure.
