    • 2 (N-N = bidentate N-donor ligand) prefer a five-coordinate trigonal-bipyramidal structure when the alkyne is a strong π-accepting ligand. Otherwise, even with rigid phenantroline ligands, the resulting Pt(II) complexes are squareplanar four-coordinated. See: Fanizzi, F. P.; Maresca, L.; Natile, G.; Lanfranchi, M.; Tiripicchio, A.; Pacchioni, G. Chem. Commun. 1992, 333-335.
