Synthesis, Magnetic Properties, and Catalytic Properties of a Nickel(II)-Dependent Biomimetic of Metallohydrolases.

ABSTRACT: A dinickel(II) complex of the ligand 1,3-bis(bis(pyridin-2-ylmethyl)amino)propan-2-ol (HL1) has been prepared and characterized to generate a functional model for nickel(II) phosphoesterase enzymes. The complex, [Ni₂(L1)(μ-OAc)(H₂O)₂](ClO₄)₂·H₂O, was characterized by microanalysis, X-ray crystallography, UV-visible, and IR absorption spectroscopy and solid state magnetic susceptibility measurements. Susceptibility studies show that the complex is antiferromagnetically coupled with the best fit parameters J = -27.4 cm^-1, g = 2.29, D = 28.4 cm^-1, comparable to corresponding values measured for the analogous dicobalt(II) complex [Co₂(L1)(μ-OAc)](ClO₄)₂·
