Two cadmium compounds containing the aspartate ligand are described, with compositions Cd(AspH)NO3 and Cd(Asp). The crystal structure of the first shows it is a two dimensional polymer in which each cadmium is coordinated to seven oxygen atoms, four from carboxylates and three from the nitrate moiety which acts both as a chelate and as a bridging ligand. For Cd(Asp), Cd-111 NMR studies suggests the presence of Cd-NH2 interaction. (C) 2002 Published by Elsevier Science Ltd.
