Abstract

Abstract The reaction of trans-[PtCl2(Me2SO)2] with 2 equivs of 1,3,5-triaza-7-phosphaadamantane (PTA) in MeNO2 at RT furnished cis-[PtCl2(PTA)2] (1) in 87% isolated yield. Corresponding reaction of K2[PtCl4] with 1 equiv. of PTA in aqueous EtOH at RT led to [PtCl(PTA)3]Cl (2) in 84% isolated yield. Complexes 1 and 2 were characterized by elemental analyses (C, H, N), HR-ESI+/−-MS, IR, 1H and 31P{1H} NMR spectroscopic techniques, and by single-crystal X-ray diffraction for 1.
