Synthesis and Crystal Structures of Two Dinuclear Nickel(II) Complexes Derived from 2-Ethoxy-6-[(2-phenylaminoethylimino)methyl]phenol

Abstract

Two nickel(II) complexes, [Ni₂L-NCS)] (1) and 2[Ni₂L-N₃)]H₂O (2), derived from the Schiff base 2-ethoxy-6-[(2-phenylaminoethylimino)methyl]phenol (HL) have been prepared and characterized by elemental analysis, IR spectra, and single crystal X-ray diffraction. Complex (1) is an end-on thiocyanato- and phenolate O-bridged dinuclear compound. Complex (2) consists of two end-on azido- and phenolate O-bridged dinuclear complex molecules and one water molecule of crystallization. The Ni atoms in the complexes are six-coordinated in octahedral geometries.
