SYNTHESIS OF ORGANOPHOSPHORUS COMPLEXES AND STRUCTURAL CHARATERIZATION OF TWO DIMERIC TRIPHENYLPHOSPHINNE COMPLEXES OF MERCURY(II) IONS FROM DIMERIC COMPLEXES OF [4-METHYLBENZOYLMETHYLENETRI-P-TOLYLPHOSPHINE MERCURY(II) HALIDES
The organophousphorus complexes of [(PPh3)2Hg2Cl4] (4), [(PPh3)2Hg2Br4] (5) and [(PPh3)2Hg2I4] (6) were resulted from nucleophilic substitution of triphenylphosphine ligand with tri-p-tolylphophine complexes (1-3). The crystal structures of two organophousphorus complexes of mercury(II) ions 4 and 6...

| Sumario: | The organophousphorus complexes of [(PPh3)2Hg2Cl4] (4), [(PPh3)2Hg2Br4] (5) and [(PPh3)2Hg2I4] (6) were resulted from nucleophilic substitution of triphenylphosphine ligand with tri-p-tolylphophine complexes (1-3). The crystal structures of two organophousphorus complexes of mercury(II) ions 4 and 6 have been determined by means of the X-ray diffraction. Both complexes were crystallized in the monoclinic space groups P2(1)/c, and have very similar bond lengths, angles pattern and same substituted triphenylphosphine ligand. Single crystal X-ray analysis of title structures reveal the presence of a centrosymmeteric dimeric structure containing the ligand and mercury halides. |
