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.
