Syntheses and structures of M(L)(X)BPh4 complexes {M=Co(II), Zn(II); L=cis-1,3,5-tris[3-(2-furyl)prop-2-enylideneamino]cyclohexane, X=0Ac, N03}: structural models of the active site of carbonic anhydrase

The metal coordination geometries in the structures of the zinc(II) and cobalt(II) complexes of the ligand cis-1,3,5-tris[3-(2-furyl)prop-2-enylideneamino]cyclohexane (fr-protach) and with the anions nitrate and acetate are structural models for the active site of carbonic anhydrase. The acetate structures show a striking structural correlation with the metal coordination environments in the known bicarbonate forms of the enzyme. Such structures provide a basis for understanding the marked effect of different metal substitution on the catalytic rate of the enzyme.
