T. Marx et al., A zwitterionic transition-metal complex: Platinum-closo-borate coordination synthesis, structure, and DFT calculations, ORGANOMETAL, 19(22), 2000, pp. 4653-4656
A zwitterionic platinum(IV) complex comprising a cationic transition-metal
center and an anionic heteroborate cluster was synthesized and structurally
characterized On. the basis of DFT calculations a dipole moment of 29.8 D
was determined for this polar molecule.
