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

F.-F. Jian and S.-J. Han

Abstract: The title compound, [Ni₂(C₁₂H₁₂N₂O₄S₃)(H₂O)₄]·2C₃H₇NO·3H₂O, 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 NiO₆ octahedral geometry arising from two O,O-bidentate ligands and two water molecules. There are intermolecular O-HO and O-HN interactions in the crystal structure. One of the uncoordinated water molecules is diordered over two sets of sites of equal occupancy.
