Zwitterionic Bimetallic Compounds

Complexes like 139 have been prepared and contain planar four-coordinate carbon atoms." " The zwitterionic early-late transition metal bimetallic species 140 has been synthesised and characterised. Little information about the structure, other than connectivity, could be inferred due to the poor nature of the crystallographic data." Heterobimetallic compounds such as 141 have been synthesised and fully characterised. Strong negative solvatachroism was observed along with high first-order hyperpolarisability The compound 142 has been prepared and crystallographically characterised. The role of planar...
