摘要：

The title compound [Cu-2(C6H3BrNO2)(4)](n), forms sheets in the bc plane. The structure features the dinuclear paddle-wheel cage motif common to copper(II) carboxylates. The polymeric structure is achieved through bridging between binuclear units by the pyridyl donors of two of the four carboxylates of the cage. Each cage engages in axial bonding at each copper atom to a pyridyl nitrogen donor and extends two 5-bromopyridine-3- carboxylate groups to bridge to adjacent binuclear sites in the bc plane. Each cage is linked to four adjacent cages in the plane. The intradimer Cu center dot center dot center dot Cu distance is 2.6465 (5) angstrom. The remaining 5-bromopyridine-3-carboxylate groups project into the interlamellar domain and interdigitate in pairs from each neighboring layer.

Unusual polymeric chains found in the single-crystal x-ray structures of [tetrakis(mu-1-phenylcyclopropane-1-carboxylato-O,O')bis(ethanol-O)dicopper(II)] and catena-poly[[bis(mu-diphenylacetato-O:O')dicopper](mu(3)-diphenylacetato-1-O:2-O':1'-O')-(mu(3)-diphenylacetato-1-O:2-O':2'-O')] [J].
