Abstract:
Two lead compounds containing the aspartate ligand are described, with compositions Pb(aspH)NO3 and Pb(asp). The crystal structure of the first shows it is a three-dimensional polymer in which each lead atom is coordinated to six oxygen atoms, five from carboxyl groups and one from a nitrate ion, For Pb(asp), spectroscopic data suggest the presence of Pb-NH2 interaction.
