文摘

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. The coordination of each zinc atom is completed by bridging carbamato, thiocarbamato or thiophosphinato groups. Disorder is observed in the zinc positions for the two sulfur-containing compounds, with zinc atoms disordered over the eight corners of a cube. The geometry of the core (μ₄-O)Zn₄ moiety is compared with ZnO and a number of related complexes.
