Nonhomoleptic complexes, dithiocarbamates

Although nonhomoleptic complexes of Sn have been extensively studied because of their considerable structural diversity and potential applications, for example, in chemotherapy, those of lead are rare. The complex [Pb(phen)(S2C-NEt2)2] (phen = 1,10-phenanthroline) is one of only a few examples of a nonhomoleptic lead(II) dithiocarbamate complex (108). The geometry at Pb (Fig. 7) is best considered as distorted trigonal bipyramidal, with the bridging S atoms occupying axial positions.
