te (HL), was prepared to synthesize nickel mimics for the active site of urease. Reaction of the deprotonated L− with Ni(ClO4)2·6H2O afforded a dinickelcomplex, [LNi2(CH3CN)(THF)](ClO4)3 (1), characterized by UV/vis spectroscopy and X-ray crystallography. Addition of urea to an acetonitrile solution of 1 afforded a dinickel urea adduct, [LNi2(urea)2](ClO4)3·2CH3CN (2), which was structurally and spectroscopically
