Abstract

The zinc(II) complex with 2-(2-hydroxyphenyl)benzimidazole, namely [Zn(2-(2-hydroxyphenyl)benzimidazolate)2]·C2H5OH (· C2H5OH) has been synthesized and characterized by X-ray crystallography and photoluminescent analysis. The complex crystallizes in monoclinic space group P21/c with cell parameters a = 10.156(1) Å, b = 25.771(3) Å, c = 9.674(1) Å, α = 90°, β = 103.641(2)°, γ = 90°, Z = 4, V = 2460.4(4) Å3. The central Zn(II) is four-coordinate and has a tetrahedral geometry. The steady-state and time-resolved photoluminescent spectra for the title compound have also been studied. The emission property can be ascribed to ligand-centered charge-transfer transition (LCCT) with π → π* property.
