In the last 2 years, a number of crystal structure determinations of molecules of the general form R2GeCl2, and where the substituents ¡ªR are not part of the same ring, have appeared [14¨C16] in the literature, all having C¨CGe¨CC angles between 120.0 and 121.48 except for one [16] which is 127.38, thus confirming that the calculated values are indeed a bit on the low side |
