Novel quinaldic acids for selective chelation of cadmium(II). X-Ray crystal structure of [Cd(C18H12NO4)2](Me2SO)·2H2O
Abstract
Quinaldic acids with a phenacyloxy group in the 8-position of the quinoline nucleus show a high selectivity for chelation of cadmium(II) forming eight-co-ordinate complexes where the carbonyl group takes part in the bonding to the metal ion.
