CRYSTAL AND MOLECULAR STRUCTURE OF PENTACOORDINATED COPPER(2) COMPLEX BIS(ACETYLACETONATO)QUINOLINECOPPER(2)

The crystal and molecular structure of bis(acetylacetonato) quinolinecopper(II), [Cμ (C5HO2)2(C9H7N)], has been determined by three dimensional methods. The cell dimensions are a = 14·23 A, b = 8·66 A, c = 8·02 A, α = 94·0°, β = 89·0°, γ = 110·8°, the space group P1 and Z = 2. The intensities of 2005 reflections were obtained visually from equi-inclination Weissenberg photographs. The structure was refined by least-squares methods with individual atom isotropic temperature factors, to a conventional R value of 0·138. The structure consists of discrete molecules containing a pentacoordinated copper atom. The donor atoms are arranged in a pyramidal configuration with four equal copper-oxygen bonds. (1·95 ± 0·01 A), directed towards the concerns of the base of a square pyramid and a fifth copper-nitrogen bond, (2·36 ± ·01 A), directed towards the apex of the pyramid. © 1969.
