Bis­{μ-3,3′-(1,3,4-thia­diazole-2,5-diyl­dithio)bis­[penta­ne­dionato(1−)]}bis­[diaqua­nickel(II)] dimethyl­formamide disolvate trihydrate

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 dimethyl­formamide and three water solvent mol­ecules. The Ni atom adopts a slightly distorted NiO(6) octahedral geometry arising from two O,O-bidentate ligands and two water molecules. There are inter­molecular O—H⋯O and O—H⋯N inter­actions in the crystal structure. One of the uncoordinated water molecules is diordered over two sets of sites of equal occupancy.
