Abstract
The reaction of [4,6-(MeO)
2pmNHLi] (pm=2-pyrimidinyl) with ‘ZnCl
2’ gives the oxo-complex [Zn
4{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 ZnMe
2 with 4,6-(MeO)
2pmNH
2 in the presence of TMEDA (Me
2NCH
2CH
2NMe
2). Attempted in situ metallation of the primary phosphide [MeZnHP
tBu]
n
using Sb(NMe
2)
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.
The primary amido– and phosphido–Zn(II) complexes [Zn
4{HN-4,6-(MeO)
2pm}
6(μ
4-O)]·4thf (
1·4thf), [Zn{HN-4,6-(MeO)
2pm}
2·TMEDA]·toluene (
2·toluene) (TMEDA=Me
2NCH
2CH
2NMe
2) and [MeZn(μ-HP
tBu)·NHMe
2]
3 (
3) have been prepared and characterised structurally. Complexes
2 and
3 are the first bis(primary)amido and primary phosphido complexes of Zn.
