摘要：

A hydrophobic pocket is formed by the residues R(Ph, tBu) in the zinc compounds L3Zn–X 1, X = NO 3⊖, CH 3⊖ and C2H5S⊖. The first unequivocally characterized hydroxocomplex of zinc [L3ZnOHZnL3](ClO4)3, L = tert‐butylpyrazole anion, was formed by hydrolysis, presumably via the intermediate cation with X = H2O. In the four complexes the whole hard/soft scale is covered with respect to the ligand X. There are structural relationships to the active centers of zinc‐containing enzymes. (Figure Presented.)
