Synthesis and spectroscopic studies of complexes of arylmercury (II) with monoand di-tertiaryphosphines/their chalcogenides

Abstract

Reactions of phenylmercury (II), PhHgX (X = Cl, NO₃, SCN, O₂CCR₃<em>, </em>R = H, F, Cl) with a series of bis(tertiary phosphines), Ph₂P(CH₂)_nPPh₂(n = 1-4) give complexes of the type PhHgXL. Similarly, RHgCI on reaction with Ph₃P, Ph₂P(CH₂)_nPPh₂ and Ph₂P(E)(CH₂)_nP(E)Ph₂ (E = S, Se; n = 1-4, R = <em>m</em>NO₂C₆H₄<em>, </em>p-CIC₆H₄) give complexes of the type RHgClL (L= mono- or bi-dentate) or (RHgCI)₂L (L = bi-dentate). Analytical, IR, NMR and molar conductance data are reported.
