Bis(μ-succinato-O,O′:O′′,O′′′)bis[bis(2-amino-1,3-benzothiazole-N³)copper(II)]

In the title dimeric complex, [Cu₂(C₄H₄O₄)₂(C₇H₆N₂S)₄], which possesses 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 closest donor atoms are two N atoms of 2-amino­benzo­thiazole ligands and two O atoms of the succinate carboxylate groups. They form a square-planar cis arrangement, with an average Cu—N distance of 2.003 (3) Å and Cu—O distances of 1.949 (3) and 1.965 (3) Å. Two longer Cu—O bonds of 2.709 (3) and 2.613 (3) Å involving the remaining O atoms of the carboxylate groups complete the sixfold coordination of the Cu atoms. The H atoms of each amino group of the 2-amino­benzo­thiazole molecules form intra- and inter­molecular N—H⋯O hydrogen bonds. A nearly perpendicular inter­molecular C—H⋯Cg interaction (Cg is the centroid of the imidazole ring) is observed. The intramolecular Cu⋯Cu distance is 6.384 (2) Å.
