[μ-2,2′-(1,4-Phenylene)diacetato-κ²O¹:O⁴]bis[aqua(2,2′-bipyridine-κ²N,N′)chloridocopper(II)] dihydrate

Abstract

Key indicators: single-crystal X-ray study; T = 296 K; mean (C-C) = 0.011 Å; R factor = 0.083; wR factor = 0.177; data-to-parameter ratio = 14.4.In the centrosymmetric title compound, [Cu 2 (C 10 H 8 O 4 )Cl 2 -(C 10 H 8 N 2 ) 2 (H 2 O) 2 ]Á2H 2 O, the Cu II atom is five-coordinated in a distorted square-pyramidal geometry by two N atoms from a chelating 2,2 0 -bipyridine ligand, one O atom from a 1,4-phenylenediacetate ligand, one Cl atom and one water molecule. The 1,4-phenylenediacetate ligand, lying on an inversion center, bridges two Cu II atoms. In the crystal, O-HÁ Á ÁO and O-HÁ Á ÁCl hydrogen bonds and -interactions between the pyridine rings [centroid-centroid distance = 3.740 (5) Å ] link the complex molecules and uncoordinated water molecules into a three-dimensional network.
