چکیده
Dinuclear Nickel(II) Complex, Binucleating Ligand The asymmetric unit of crystal of the title compound, [Ni2(L)(C3H 3N2)j (L = 1,3-Bis(2hydroxy-4-methoxybenzylideneamino)propan-2-ol, C3H 3N 2 = pyrazolate) contains two inde pendent dinickel(II) complexes. In both molecules, the nickel(II) ions are bridged by the alkoxo group of the ligand and the N atoms of the pyrazolate group. Each nickel(II) ion is coordinated by two N and two O atoms, forming a square with trans-N 20 2 geometry.
