3,5-DINITRO-BENZOATO-O-O')(METHANOL-O)COPPER(II)]]

The title complex, [Cu-3{(NO2)(2)C6(H?3)COO}(6)(CH3OH)(2)](n), is a li near polymeric chain with the dinitrobenzoate ions forming all bridges . The chain is linked across Cu(CH3OH)(2) units on symmetry centres an d includes fourfold bridged pairs of Cu atoms with a Cu ... Cu separat ion of 2.616 (2) Angstrom. The latter Cu atoms are five-coordinated, s urrounded by square pyramids of carboxylate O atoms, each with a long apical Cu-O distance of 2.169 (2)Angstrom and four short basal Cu-O di stances in the range 1.951 (3)-1.959 (2) Angstrom. The coordination in the Cu(CH3OH)(2) unit is completed by two carboxylate O atoms to give a square-planar arrangement, with Cu-O distances of 1.933 (2) and 1.9 37 (2) Angstrom.
