An unprecedented coordination mode of the orotate ligand in novel polynuclear cadmium(II)-orotate complexes

We have successfully synthesized the polynuclear cadmium(II)-orotate complexes Cd(μ-HOr)(2-etapy)]n and {[Cd(μ-HOr)(H2O)(N,N-eten)]·H2O}n. In the complexes, the orotate ligand exhibits a new coordination mode in addition to the 23 different modes so far crystallographically characterized.
