Abstract
In the title polymeric compound, [Cu(C 9H 6O 4)(C 3H 4N 2) 2] n , the copper(II) cation occupies an N 2O 3 coordination sphere defined by two 1H-imidazole (imid) ligands in trans positions and three carboxyl-ate O atoms from three different 2-(car-boxyl-atometh-yl)benzoate (hpt 2-) dianions. The geometry is that of a square pyramid with one of the O atoms at the apex, bridging neighbouring metal centres into an [-ON 2CuO 2CuN 2O-] dinuclear unit. These units are in turn connected by hpt anions into a reticular mesh topologically characterized by two types of loops, viz. a four-membered Cu 2O 2 diamond motif and a 32-membered Cu 4O 8C 20 ring. The imid groups do not take part in the formation of the two-dimensional structure, but take part in the N-H?O interactions. These arise only within individual planes, inter-planar inter-actions being only of the van der Waals type. © 2011 International Union of Crystallography.
