Abstract

Reactions of [Pt(SeC5H4N)2(P∩P)] with M(OAc)2.2H2O/MX2 (P∩P = dppm, dppp; M = Zn, Cd, Hg, Cu; X = Cl) resulted various products depend upon the nature of the phosphine. In case of dppm, reaction between [Pt(SeC5H4N)2(dppm)] and M(OAc)2.2H2O/MX2 (M = Zn, Cd, Hg) afforded an exchange product of composition [PtCl2(dppm)]. Similarly, the reaction with ‘dppp’ analog yielded an adduct [{Pt(SeC5H4N)2(dppp)}MX2] (M = Cd, Hg, Cu; X = Cl, OAc). Whereas, reaction with Zn(OAc)2, on extraction with dichloromethane resulted the product with the loss of one selenium atom of composition [{Pt(C5H4N)(SeC5H4N)(dppp)}ZnCl2]. These complexes were characterized by elemental analyses and NMR (1H, 31P, 77Se, 195Pt) spectroscopy. The molecular structure of [{Pt(C5H4N)(SeC5H4N)(dppp)}ZnCl2] was established by single crystal X-ray diffraction analyses.
