Synthesis and Structural Studies of Dinuclear Ni(Ii) Complexes as Models For Urease. Raza Khan, Yilma Gultneh, Syed M. Mahmood and Ray J. Butcher, Chemistry Dept., Howard University, Washington, DC 20059 USA

We have synthesized and structurally characterized dinuclear Ni(II) complexes of chelating pyridyl and phenolate donor ligands. The structures, metal-metal interactions and the effects of these in determining the properties of the complexes in modeling the dinuclear active site of urease are studied.
