Bis(mu-succinato-O,O': O",O"')bis[bis(2-amino-1,3-benzothiazole-N-3)copper(II)]

In the title dimeric complex, [Cu-2(C4H4O4)(2)(C7H6N2S)(4)](,) which posses ses a centre of symmetry, the Cu atoms are enclosed in a 14-membered ring. They adopt a distorted square-bipyramidal (4+2) coordination. The four clos est donor atoms are two N atoms of 2-aminobenzothiazole ligands and two O a toms of the succinate carboxylate groups. They form a square-planar cis arr angement, with an average Cu-N distance of 2.003 (3) Angstrom and Cu-O dist ances of 1.949 (3) and 1.965 (3) Angstrom. Two longer Cu-O bonds of 2.709 ( 3) and 2.613 (3) Angstrom involving the remaining O atoms of the carboxylat e groups complete the sixfold coordination of the Cu atoms. The H atoms of each amino group of the 2-aminobenzothiazole molecules form intra- and inte rmolecular N-H ... O hydrogen bonds. A nearly perpendicular intermolecular C-H ... Cg interaction (Cg is the centroid of the imidazole ring) is observ ed. The intramolecular Cu ... Cu distance is 6.384 (2) Angstrom.
