Synthesis and Crystal Structure of A New Dinuclear Cu(II) Complex

Abstract

A new dinuclear copper(II) complex was synthesized by reaction of 5,5‐diphenylimidazoline‐2,4‐dione (phenytoin, PHT), 3‐amino‐1‐propanol(PA) and copper acetate. Its crystal structure was determined by single crystal X‐ray diffraction. The compound crystallizes in the monoclinic system, space group C2/c with a=28.429(10), b=8.328(3), c=17.863(7) Å, β=111.189(6)°; V=3943(2) Å3, Mr=833.87, Z=4, F(000)=1736, Dc=1.405 g/cm3, μ=1.137 mm−1, the final R=0.0699 and wR=0.1737. The symmetric unit is comprised of four molecules. The complex is a centrosymmetric plane in which each copper(II) is coordinated in the quadrilateral plane to the ligand phenytoin through the deprotonated oxygen atom of 3‐amino‐1‐propanol as well as the nitrogen atoms of imine and amine. The Cu(II)…Cu(II) average distance is 3.005 (19) Å.
