dc.description.abstract[TpPh,MeNi(Cl)PzPh,MeH] (1) has been synthesized by the reaction of hydrotris(3-phenyl-5-methyl-pyrazol-1-yl) borate [Tp Ph,Me], NiCl2 • 6H2O and 3-phenyl-5-methyl-pyrazole [PzPh,MeH]. The reaction of 1 with variously substituted sodium p-X-benzoates resulted in the formation of complexes of the type [TpPh,MeNi(p-X-OBz)PzPh,MeH] (X = H for 2, F for 3, Cl for 4, NO2 for 5, Me for 6, OMe for 7, OH for 8, CHO for 9 and CN for 10). Single crystal X-ray studies suggest that all these complexes have a five-coordinate metal center and the benzoate groups are monodentate in a square pyramidal geometry. The X-ray studies also reveal that the uncoordinated oxygen atom of the benzoate forms intramolecular hydrogen-bonds with the NH group of the coordinated pyrazole. The substituents present on the benzoate ring are involved in different types of intermolecular interactions and the complexes exhibit different crystal packing. Complexes 2-10 were tested for superoxide dismutase activity. © 2009 Springer Science+Business Media B.V.-
