Calcium, strontium, and barium compounds involving heavy group 14 ligands have been recognized as useful initiators in the polymerization of acrylonitrile. Since little is known on the exact nature of the target compounds, including information on synthetic access and spectroscopic and structural details, we have prepared and characterized the first calcium, strontium, and barium germanides of the general formula M(THF)n(Ge(SiMe3)3)2 (M = Ca, n = 3, 1; Sr, n = 3, 2; and Ba, n = 4, 3). The title compounds are available by a convenient one-pot metathesis reaction.
