title: Bis[1,3-bis-(1-methyl-1H-benzimidazol-2-yl)-2-oxapropane]-cadmium dipicrate acetonitrile sesquisolvate 0.25-hydrate.
abstract: In the title compound, [Cd(C(18)H(18)N(4)O)(2)](C(6)H(2)N(3)O(7))(2)·1.5CH(3)CN·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 octa-hedral coordination environment. The lengths of the chemically equivalent Cd-O bonds [2.4850 (16) and 2.5488 (16)Å] 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 mol-ecule is disordered over two sites with equal occupancies. The H atoms of a 0.25-occupancy solvent water mol-ecule were neither located nor included in the refinement.
