Abstract: | Summary The preparation and properties of the following neutral and cationic compounds containing Pt-Hg bonds is described: (PPh3)2ClPt-HgR] (R=2,4,6-C6H2Cl3; 2,3,4,6- and 2,3,5,6-C6HCl4 and C6Cl5), and (PPh3)2LPt-Hg(C6Cl5)]ClO4 (L=pyridine, , and -picoline; 2,4-lutidine and -colidine). All the compounds have been characterized by31P n.m.r. spectroscopy. The dependence of P, J(31P-195Pt) and2J(31P-199Hg) on the slight changes of the electronic properties of the ligands L and R has been studied. |
