New mono and binuclear mercury(II) complexes of phosphorus ylides containing DMSO as ligand: Spectral and structural characterization

Four-coordinate and pseudo five-coordinate Hg(II) complexes of a new bidentate phosphorus ylide: X-ray crystal structure and spectral characterization

“…C(26)-P(2)-C(1)-P(1) moiety}. The changes in bond lengths and bond angles calculated here are very similar to those observed for the complexes of similar ylides [13,18]. As we explained in previous sections the complex 6 is the product of the crystallization of the compound 4 in DMSO solution.…”

“…Hg(II) forms C-coordinated complexes with X-C 6 H 4 C(O)C(H)@ PAr 3 (X = Cl and NO 2 ; Ar = phenyl and p-tolyl) [18,19] and Ph 3 P@C(H)CO(OEt) [20]. On the other hand, regiospecific O-coordination of the acetyl oxygen has been observed for the reaction of Hg(II) halides with Ph 3 P@C(COPh)(COMe) [21].…”

“…The investigation of the reactivity and coordination chemistry of carbonyl stabilized ylides is research field of our group [18][19]24]. We have now focused our attention to new bidentate phosphorus ylides.…”

Synthesis, characterization, crystal structure, theoretical studies, and antibacterial activities of P-coordinated mercury(II) complexes containing phosphine–phosphonium salts

“…The phosphonium salts are most often converted to phosphorus ylides by releasing a proton. The efficiency of metalated phosphorus ylides in synthetic chemistry has been well documented [19][20][21][22][23][24][25][26][27]. Most of the interest in the coordination properties of resonance stabilized phosphorus ylides stemming from their bond versatility is due to the presence of different functional groups in their molecular structure [20].…”

31P NMR study of the stoichiometry and stability of several mercury(II) halides with a phosphorus ylide in different solvents

“…In 1975, Weleski et al [16] proposed a symmetric halidebridged dimeric structure for Hg(II) halide complexes whereas Kalyanasundari et al [17] reported an asymmetric halidebridged dimeric structure in 1995. We have recently focused on the synthesis of mononuclear [18], binuclear [19,20] and polynuclear complexes derived from mercury(II) salts and phosphorus ylides.…”
