The reaction of COS gas with a suspension of [M(OMe)2]Ξ· (M = Mg and Ca) in methanol yields the insertion compounds, [M(OCSOMe)2(MeOH)x]Ξ· (M = Mg 1, View the MathML source) in high yield; the magnesium compound is polymeric, whilst X-ray crystallography reveals that the calcium complex 2 is a centrosymmetric dimer with eight coordinated calcium(II) ions and two distinct methylthiocarbonato (MTC) ligand coordinations modes, the structural framework being stabilised by an extensive network of hydrogen bonding.
