چکیده
In the title carboxyl-ate-bridged binuclear copper complex, [Cu(2)(C(4)H(5)O(2))(4)(C(5)H(6)N(2))(2)], each Cu(II) ion has a distorted square-based pyramidal environment formed by one N and four O atoms. The asymmetric unit contains two halves of two centrosymmetric mol-ecules, with Cu⋯Cu separations of 2.6498 (8) and 2.6528 (8) Å.

The complete dinuclear mol-ecule of the title complex, [Cu(2)(CH(3)COO)(4)(C(12)H(12)N(2))(2)], is generated by a centre of inversion. The Cu(II) atoms are connected [Cu-Cu = 2.6329 (16) Å] and bridged by four acetate ligands. The distorted octa-hedral coordination geometry is completed by a terminal pyridine N atom. The amine H atom forms an intra-molecular N-H⋯O hydrogen bond.
