Novel alkylmetal hydroxides. The crystal and molecular structures of bis(µ-hydroxy)-bis{tris(dimethylphenylsilyl)methylzinc}, [{Me2PhSi)3CZnOH}2] and µ4-oxohexa(µ-hydroxy)tetrakis{tris(trimethylsilyl)methylindium}, [O{(Me3Si)3Cln}4(OH)6]

The compounds [{(Me2PhSi)3CZnOH}2] and [O{(Me3Si)3Cln}4(OH)6] have been shown by X-ray diffraction to have structures based on four-membered M2O2-rings (M = Zn or ln).
