Abstract

The reaction of [4,6-(MeO)₂pmNHLi] (pm=2-pyrimidinyl) with 'ZnCl₂' gives the oxo-complex [Zn₄{HN-4,6-(MeO) ₂pm}₆(₄-O)]·4thf (1·4thf), containing a tetrahedral arrangement of four Zn centres which surround a central O^2- ion, as a result of the presence of lattice hydrolysis of the Zn salt. The bis(primary)amido complex [Zn{HN-4,6-(MeO) ₂pm}₂·TMEDA] (2) is obtained as its toluene solvate (2·toluene) by the reaction of ZnMe₂ with 4,6-(MeO)₂pmNH₂ in the presence of TMEDA (Me ₂NCH₂CH₂NMe₂). Attempted in situ metallation of the primary phosphide [MeZnHP^tBu]_n using Sb(NMe₂)₃ gives rise to the trimeric, Me ₂NH-solvated complex [MeZn(μ-HP^tBu)·NHMe ₂]₃ (3). The solid-state structures of 1, 2 and 3 are reported. Complexes 2 and 3 are the first bis(primary)amido and primary phosphido complexes of Zn.
