Synthesis and Crystal Structure of Chloro{bis[N,N′-(2-chlorobenzylidene)]-ethylenediamine}(triphenylphosphine)]copper(I)

Abstract

The crystal structure of CuL(PPh₃)Cl (L = bis(N,N′-2-chlorobenzylidene)ethylenediamine) was determined by an X-ray diffraction method. The title copper(I) complex crystallizes in the monoclinic space group P2₁/n with cell parameters a = 10.2203(9), b = 21.545(6), c = 14.060(3)Å, β = 101.854(10), V = 3030.1(10)ų and Z = 4. The structure was refined to the final R1 = 0.0320 using all 6931 observed reflections. The coordination polyhedron around the Cu^I center in this complex is best described as a distorted tetrahedron.
