Diphenyl ketimine derivatives as a probe for Group IV pπ–dπ bonding: the structures of M(NCPh2)4(M = Si, Ge, Sn)
Abstract
The crystal structures of the three title compounds have been determined; the dramatic differences in their M–N–C bond angles suggest that Si is subsantially involved in pπ–dπ bonding, that Ge is partially involved, and that Sn shows no pπ–dπ bonding.
