Abstract The crystal structures of dodecaphenyl-cyclohexastannane (Ph 2 Sn) 6 and dodecabenzyl-cyclohexastannane dimethylformamide (Bz 2 Sn) 6· DMF have been determined. The molecules of (Ph 2 Sn) 6 show, in contrast to those of (Ph 2 Sn) 6· 2toluene and (Bz 2 Sn) 6· DMF, remarkable differences in the chair conformation indicated by the ring torsion angles and the bond angles. The tin—tin bonds of (Bz 2 Sn) 6· DMF are somewhat ...
