The crystal structures of [CuCl(totp)]2 and [CuBr(totp)]2, totp=tri-o-tolylphosphine, are reported. They present planar Cu2X2 cores with trigonal-planar Cu(I) atoms, the Cuξ—ΈP axes bisecting in both cases the Xξ—ΈCuξ—ΈX angles. Crystallographic data: for [CuCl(totp)]2a = 9.1758(7), b = 10.4805(8), c = 20.481(1) Γ…, Ξ² = 99.279(2)Β°, with Z = 2 and space group P21/n; for [CuBr(totp)]2a = 9.215(1), b = 10.203(1), c = 11.275(1) Γ…, Ξ± = 78.422(5), Ξ² = 100.691(5), Ξ³ = 80.789(4)Β°, with Z = 1 and space group PView the MathML source. The slight geometric changes observed between the two compounds, especially the more acute Xξ—ΈCuξ—ΈX angle in the case of [CuCl(totp)]2 are investigated with Extended HΓΌckel calculations on model compounds.
