Abstract

The (P, S) ligand 1-(ethylthio)-2-(diphenylphosphino) ethane (L) is synthesized by reacting Ph2PLi with CH3CH2SCH2CH2Cl. The yield is good (similar to 85%) and the method of preparation is simpler than the liquid ammonia based one reported earlier. Its complexation with Cu(I), Hg(II) and organometallic species of Ru(II) are explored. All the complexes and the ligand exhibit characteristic proton, carbon-13 and phosphorus-31 NMR spectra. The single crystal structure of the Hg(II) complex has been determined. It is found to be a three coordinate complex. The sum of the bond angles at Hg, viz. P(1)-Hg(1)-Br(1), P(1)-Hg(1)-Br(2) and Br(1)-Hg(1)-Br(2), is approximate to 360 degrees. Thus the geometry around Hg can best be described as essentially trigonal planar. The Hg(1)-P(1) bond length is 2.415(1) angstrom and the Hg-Br bond lengths are 2.5152(6) and 2.5952(6) angstrom. There exists a weak secondary interaction between Hg and the S donor site of the ligand [Hg(1)•••S(1) bond distance 3.063(1) Å < sum of van der Waal's radii 3.35 Å].
