- Abstract
- Crystal complexes CuCl · AAO (I) and CuBr · AAO (II) (AAO = allylacetone oxime) were prepared by ac electrochemical synthesis from ethanol solutions of CuCl2 · 2H2O or CuBr2 and AAO, and their crystal structures were determined [a DARCh diffractometer, MoKα radiation, 1409 and 930 independent reflections with F ≥ 4σ(F), R= 0.048 and 0.037 for I and II, respectively]. The crystals of the isostructural complexes are monoclinic, space group P21/a, Z = 4. Unit cell parameters for I are a = 15.606(6), b = 7.782(4), c = 7.480(7) Å, β = 111.46(5)°, V = 845(2) Å3; for II they are a = 16.014(5), b = 7.920(3), c = 7.504(2) Å, β= 111.27(2)°, V = 887(1) Å3. In both structures, the copper atom is simultaneously π- and σ-coordinated and has a trigonal-pyramidal environment constituted of the oxime nitrogen atom, a halogen atom and the C=C bond in the equatorial plane, and an apical halogen atom. The lengths of the coordinated C=C bonds are 1.35(1) (I) and 1.35(2) (II) Å. © 1998 MAEe Cyrillic signK Haκa/Interperiodica Publishing.
