Stabilisation of unusual metal co-ordination geometries using an oxo-cubane ligand; syntheses and structures of [{Sn4(NtBu)3O}3LiCl]·3thf and [{Sn4(NtBu)3O}3FeCl2]·3thf
Abstract
Complexation of LiCl and FeCl2 with the oxo-cubane [Sn4(NtBu)3O] 1 (3 equivalents) gave [{Sn4(NtBu)3O}3LiCl]· 3thf 2 and [{Sn4(NtBu)3O}3FeCl2]·3thf 3, respectively; the co-ordination of three sterically demanding, ‘
