Abstract
Crystals of the title compound, [Cr(C4H5NO4)(C6H6N4S2)(H2O)]Cl.H2O, consist of Cr(III) complex cations, Cl- counter-ions and lattice water molecules. The complex cation assumes an octahedral coordination geometry, formed by a tridentate iminodiacetate dianion (IDA), a diaminobithiazole (DABT) molecule and a water molecule. The planar DABT group chelates the Cr(III) ion with normal Cr-N distances [2.0574 (17) and 2.0598 (17) A], but the DABT molecule is inclined to the coordination plane by a dihedral angle of 17.23 (7) degrees. In the monodentate carboxylate groups of the IDA ion, the coordinated C-O bonds [1.288 (3) and 1.284 (3) A] are much longer than the uncoordinated C-O bonds [1.222 (3) and 1.225 (3) A].
