Abstract
The magnetic susceptibilities of a number of binuclear nickel(II) complexes between 80 and 300°K are reported. Most of the compounds exhibit antiferromagnetic exchange, and a curve-fitting procedure is used to obtain values of the exchange parameter J. The compounds studied include Ni2 paa3X4,nH2O (paa = pyridine-2-aldazine; X = I, ClO4, or BF4), Ni2 dppn2X4,nH2O (dppn = 3,6-di(pyrid-2-yl)pyridazine; X = NO3 or ClO4), Ni2 dppl(NO3)2,2H2O [dppIH = 3,5-di(pyrid-2-yl)pyrazole, a new compound], Ni2 dhph2X4,nH2O (dhph = 1,4-dihydrazinophthalazine; X = Cl, Br, or I), and Ni2 en4(C2O4)(NO3)2. The values of J for these and other binuclear nickel(II) complexes are discussed in terms of superexchange mechanisms.Keywords
