• COMPLEXES

In the title mononuclear cadmium complex, [Cd(C10H5O4)(2)(H2O)(2)], the Cd-II atom, located on a crystallographic inversion center, exhibits a slightly distorted octahedral geometry and is six-coordinated by two O atoms from water molecules in the axial positions and four O atoms from two deprotonated coumarin-3-carboxylic acid ligands in the equatorial plane. Angles around the Cd-II atom vary between 81.00 (5) and 99.00 (0)degrees. The Cd-O bond lengths vary between 2.1961 (13) and 2.3360 (13) angstrom. O-H center dot center dot center dot O hydrogen bonds between the H atoms of coordinated water molecules and the O atoms of carboxylate groups link the complex molecules into layers parallel to the ab plane.
