The adoption of the beryllium acetate structural motif in zinc oxycarbamates, oxythiocarbamates and oxythiophosphinates

Zn4OL6(L = S2CNEt2, S2PEt2 and OCNEt2) complexes are readily formed by hydrolysis of the mixed alkylzinc-carbamato, thiophophinato or thiocabamato (RZnL) compounds. These oxyzinc complexes all adapt a basic beryllium-acetate-like tetrahedral (μ4-O)Zn4 core.
