title: Bis-{μ-3,3'-(1,3,4-thia-diazole-2,5-diyl-dithio)bis-[penta-ne-dionato(1-)]}bis-[diaqua-nickel(II)] dimethyl-formamide disolvate trihydrate.
abstract: The title compound, [Ni(2)(C(12)H(12)N(2)O(4)S(3))(H(2)O)(4)]·2C(3)H(7)NO·3H(2)O, is made up of a centrosymmetric, bimetallic complex containing a 24-membered macrocyclic ring, two dimethyl-formamide and three water solvent mol-ecules. The Ni atom adopts a slightly distorted NiO(6) octahedral geometry arising from two O,O-bidentate ligands and two water molecules. There are inter-molecular O-H⋯O and O-H⋯N inter-actions in the crystal structure. One of the uncoordinated water molecules is diordered over two sets of sites of equal occupancy.
