Bis[1,3-bis(1-methyl-1H-benzimidazol-2-yl)-2-oxapropane]cadmium dipicrate acetonitrile sesquisolvate 0.25-hydrate

In the title compound, [Cd(C18H18N4O)(2)](C6H2N3O7)(2)(center dot)-1.5CH(3)CN center dot 0.25H(2)O, the Cd-II ion is coordinated by four N atoms and two O atoms from two tridentate 1,3-bis(1-methyl-1H-benzimidazol-2-yl)-2-oxopropane ligands in a distorted octahedral coordination environment. The lengths of the chemically equivalent Cd-O bonds [2.4850 (16) and 2.5488 (16)angstrom] are signiificantly different. One of the picrate anions is disordered over two sets of sites, with refined occupancies of 0.504 (15) and 0.496 (15). A 0.5-occupancy acetonitrile solvent molecule is disordered over two sites with equal occupancies. The H atoms of a 0.25-occupancy solvent water molecule were neither located nor included in the refinement.
