Synthesis, Crystal Structure, and Fluorescence of a Novel Trinuclear Zinc(II) Complex Derived From 2-Ethoxy-6-[(2-phenylaminoethylimino)methyl]phenol

Abstract

A novel trinuclear zinc(II) complex, [Zn₃L₃(μ₃-O)]·ClO₄·H₂O, where L is the anionic form of 2-ethoxy-6-[(2-phenylaminoethylimino)methyl]phenol, has been synthesized and characterized by elemental analysis, FT-IR spectra, and single-crystal X-ray determination. The crystal of the complex is cubic: space group P2₁3, a = b = c = 17.6479(2) Å, V = 5496.4(1) ų, Z = 4, R₁ = 0.0759, wR₂ = 0.1963. The Zn···Zn distance is 3.134(1) Å. The Zn atom is coordinated by one imino N, one amino N, and two phenolate O atoms from the Schiff base ligand, and one bridging O atom, forming distorted trigonal-bipyramidal geometry. Fluorescence of the complex was also studied.
