(-5-Carboxybenzene-1,3-dicarboxylato-²O¹:O³)bis[bis(2,2'-bipyridine-²N,N')copper(II)] 5-carboxybenzene-1,3-dicarboxylate 2,2'-bipyridine solvate tridecahydrate

Abstract: The asymmetric unit of the title complex, [Cu₂(C₉H₄O₆)(C₁₀H₈N₂)₄](C₉H₄O₆)·C₁₀H₈N₂·13H₂O, comprises two formula units. The two Cu^II centres are bridged by a 5-carboxybenzene-1,3-dicarboxylate (Hbtc) ligand. Each of the metal centres is bonded to four N atoms of two bidentate 2,2'-bipyridine ligands (bpy) and one O atom of the Hbtc ligand in a highly distorted square-pyramidal geometry. The secondary structure is stabilized by a variety of O-HO hydrogen bonds and - stacking interactions connecting the complex cations, Hbtc anions, bpy and water molecules of crystallization. Three water molecules are disordered over two positions, with site occupancy factors of ca 0.8 and 0.2.
