Abstract

The reaction of mercury(II) halides with the phosphine-phosphonium salts [PPh2(CH2)2PPh2CH2C(O)C6H4R]Br (R = Br (S1), NO2 (S2) in methanol affords the zwitterionic mercury(II) complexes {HgX2Br(PPh2(CH2)2PPh2CH2C(O)C6H4R)} [R = Br: X = Cl (1), Br (2), I (3); R = NO2: X = Cl (4), Br (5), I (6)]. These complexes were fully characterized by elemental analysis and spectroscopic techniques such as IR, 1H, 31P, and 13C NMR. The structure of complex 4 has been characterized crystallographically. Single crystal X-ray analysis reveals the presence of mononuclear P-coordinated complex containing Hg(II) in a distorted tetrahedral environment. Theoretical studies using density functional theory have bee..
