Abstract
A bulky, unsymmetrical beta-diketiminate ligand, [HC{MeN(Dip)}{MeN(TCHP)}]- (Dip/TCHPNacnac; Dip = 2,6-diisopropylphenyl, TCHP = 2,4,6-tricyclohexylphenyl), has been utilised in the preparation of a series of magnesium alkyl and calcium, strontium and barium amide complexes. Reaction of these with PhSiH3 afforded the first complete series of beta-diketiminato heavier group 2 metal hydride complexes, [{(Dip/TCHPNacnac)M(mu-H)}2] (M = Mg, Ca, Sr or Ba). The unsymmetrical nature of the beta-diketiminate ligand seemingly promotes stabilising interactions of ligand Dip groups with the metal centres in the Ca, Sr and Ba hydride complexes.
