μ-Alkoxo-μ-pyrazolato-bridged binuclear nickel(II) complexes with 1,3-bis(salicylideneamino)-2-propanol (H3L_a), 1,4-bis(salicylideneamino)-2-butanol (H3L_b), and 1,5-bis(salicylideneamino)-3-pentanol (H3L_c), Ni2(L_a)(pz), Ni2(L_b)(pz), and Ni2(L_c)(pz) (pz = pyrazolate anion), have been prepared and characterized by elemental analyses, infrared and electronic spectra, and magnetic susceptibilities.The molecular structures of these complexes were determined by the single-crystal X-ray structure analyses.The planarities of the molecules were discussed in relation to the variation of the chain lengths of the Schiff bases.
