title: Di-μ-chlorido-bis-[chlorido(1,4,6-trimethyl-6-nitro-1,4-diazepine)copper(II)].
abstract: The title neutral copper complex, [Cu(2)Cl(4)(C(8)H(17)N(3)O(2))(2)], shows a binuclear center with a Cu-(μ-Cl)(2)-Cu core, in which each copper ion is coordinated by the N,N,O donor atoms of the tridentate ligand 1,4,6-trimethyl-6-nitro-1,4-diazepine (meaaz-NO(2)) and three chloride exogenous ligands. Each metal ion is facially coordinated by meaaz-NO(2) through N,N,O donor atoms, whereas two bridging and one terminal chloride ions occupy the other face of the highly Jahn-Teller-distorted octa-hedron. Two N atoms from tertiary amine groups of the meaaz-NO(2) ligand and two exogenous Cl atoms with short Cu-N and Cu-Cl distances define the equatorial plane. The coordination around each Cu(II) ion is completed by another Cl atom and an O atom from the NO(2) group, in the axial positions. The binuclear complex exhibits a centrosymmetric structure with point symmetry .
