Preparation and characterization of mercury [II] -keto stabilized ylides complexes

Two new series of mercury [II]-Ylides Complexes were prepared from phosphoranes and sulphuranes with mercury [II] chloride. The complexes have the general formula [Hg L C1[2]] and [Hg L[2] G1[2], where L = bidentate phosphorane or sulforane ligands. The prepared complexes were characterized by elemental analysis and conductance measurements. The IR-spectra of the complexes showed that both C=-O and S or ph[3]P coordinate to the central mercury [II] ion on complex formation. Electronic and 1H-NMR spectra of the complexes were also made use of to study the ligated groups around the central mercury [II] ion
