چکیده
The title binuclear complex, [Cu(2)(C(2)H(3)O(2))(4)(C(6)H(9)N(3))(2)], lies on an inversion center with four acetate ligands bridging two Cu(II) ions and two monodentate N,N-dimethyl-pyrazine-2-amine ligands coordinating each Cu(II) ion via N atoms, forming slightly distorted square-pyramidal environments.

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.
