The mass spectrum of oxalato(1R, 2R-cyclohexanediamine ) Pt has been studied by electrospray ionization (ES), electronic ionization (EI) and fast atom bombardment (FAB) techniques, respectively. The possible mechanism of the fragmentation process is discussed. The complex has also been characterized with its TG-DTA spectra.
A few copper? ions or groups have been designed and investigated for metal assisted self assembly. Reactions of these metal units with a number of linear bridging ligands have led to the production of some dinuclear copper? complexes and coordination polymers in which metal centers are all five coordinate in the configuration of a square pyramid or a triangular bipyramid.
