The active site model compounds [η^3-HB(3-Phpz)3ZnX][X=Cl^-(1), Br^-(2), I^-(3), NO3^-(4)] of the carbonic anhydrase have been prepared and characterized by elemental analysis, IR, ^1H NMR spectrum. The molecular orbital, bood grade and the atomic charge of the model compound 2 as well as the model [η^3-HB(3-Phpz)3ZnOH] were calculated by DV-Xα method. According to the calculated results the active atoms and active groups in model compounds are discussed.
