Mercury complexes tellurium ligands

Complexes of the following elements with dialkyl and/or diaryl telluriums have been prepared B, Ga, Sn, V, Ta, Cr, Mo, Mn, Re, Fe, Ru, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Cd, and Hg. Examples of coordination compounds with diorgano telluriums as ligands are given in Table 14 (p. 489). The adducts of mercury(II) halides with diorgano telluriums were used in ihe older literature to separate diorgano telluriums from reaction mixtures (Vol. IX, p. 1057). 

Tellurium coordination is seen in a series of acychc bidentate ligands that coordinate through Te N donor atoms or Te donor atoms An interesting series of adamantane-like cage complex cations that contain mercury(II) have been prepared and have the general formula [ j,-ER2(HgL)4] + (E = S, Se,orTe L = phosphine or arsine). These cations contain a variety of Hg-L bonds and have been characterized using heteronuclear NMR ( P, Te, Hg).
