The attempted synthesis of homoleptic bis(2,6-dimethoxyphenyl)calcium reproducibly yielded a cryst. product Ar6Ca4O (Ar = 2,6-dimethoxyphenyl), in which the Ca2+ ions span a tetrahedron, the six aryl ligands bridge the vertexes, and O2- occupies the center. Its structure was detd. by x-ray crystallog.
