The title lead(II) derivative was obtained as dark blue crystals by treatment of PbCl 2 with (TMEDA = N, N, N ‘, N ‘-tetramethylethylenediamine) in tetrahydrofuran and its structure determined by X-ray diffraction. The compound is in effect the first dialkylead(II) species to be structurally characterized. The C−Pb−C angle is 117.1(2)°. Analogous treatment of SnCl 2 yielded a yellow solid, which was judged from spectroscopic data to be the TMEDA complex of the analogous stannacycloalkane.
