CRYSTALLOGRAPHIC ANALYSIS OF A SAMARIUM(III) COMPLEX WITH 1,3,5-TRIS(1-IMIDAZOLYL)BENZENE

Abstract

In this paper, a new samarium(III) complex with 1,3,5-tris(1-imidazolyl)benzene(tib) was synthesized via the solvent thermal reaction. The single crystal of the complex is measured by X-ray diffraction and subjected to crystallographic and conformational analyses. The crystal is monoclinic: a = 8.5589(12) A, b = 12.2883(14) A, c = 21.109(3) A, α = 90°, β = 98.585(4)°, γ = 90°, V = 2195.3(5) A3, space group P21/n, Z = 4, ρc = 2.044 mg/m3, R = 0.0513. The asymmetric unit contains one samarium(III) center, eight O atoms from nitrate ions in solvent, and two N atoms from two different tib ligands.
