Bis(2,2′-bipyridine-κ2N,N′)bis[3-(3-hydroxyphenyl)propenoato-κ2O1,O1′]cadmium

Abstract

The title compound, [Cd(C9H7O3)2(C10H8N2)2], was synthesized under mild hydrothermal conditions. The structure of the complex molecule consists of four approximately planar fragments: two 3-(3-hydroxyphenyl)propenoate residues and two 2,2′-bipyridine ligands [largest deviation from the least-squares planes is 0.240 (1) Å for one of 3-(3-hydroxyphenyl)propenoate residues]. The dihedral angles formed by the least-squares planes of the 2,2′-bipyridine ligands and the opposite 3-(3-hydroxyphenyl)propenoate residues are 22.68 (7) and 26.47 (6)°. The CdN4O4 coordination polyhedron can be described as distorted dodecahedral. Intermolecular O—H...O hydrogen bonds between carboxylate O atoms and hydroxy groups lead to the formation of chains along the a-axis direction.
