✦ Synopsis

The title compound, {(C 10 H 10 N 2 )[Cu 2 (C 5 HN 2 O 4 ) 2 ]} n , has been synthesized under hydrothermal conditions. The self-assembly of the pyrazole-3,5-dicarboxylate ligands and Cu II atoms results in a one-dimensional anionic chain, in which the Cu II atom is five-coordinate in a square-pyramidal geometry. The doubly protonated 4,4 0 -bipyridine (bpy) cation lies on an inversion center. A two-dimensional supramolecular network is formed through N-HÁ Á ÁO hydrogen bonds between the bpy cations and the uncoordinated carboxylate O atoms of the polymeric anions. The dinuclear repeat unit with two bridging pyrazole rings is centrosymmetric.
