- Abstract
- The crystals of the 2CuCl·AAAZ (I) and 2CuBr·AAAZ (II) complexes were prepared by ac electrochemical synthesis from CuCl2·2H2O or CuBr2 in ethanol-2-butanol mixture and from allylacetone azine (AAAZ) and structurally characterized (DARCh diffractometer, MoKα radiation, 1091 and 738 independent reflections with F ≥ 4σ(F), R = 0.027 and 0.034 for I and II, respectively). The crystals of the isostructural compounds are orthorhombic, space group Pcab, Z = 8. Unit cell parameters for I: a = 19.199(7), b = 11.780(5), c = 13.493(4) Å, V = 3052(3) Å3; for II: a = 19.264(4), b = 12.340(8), c = 13.591(4) Å, V = 3231(4) Å3. In both structures, the ligand is both π- and σ-coordinated to the copper atom, whose trigonal-pyramidal surroundings consists of the nitrogen and halogen atoms and C=C bond in the equatorial plane and apical halogen atom. One of the coordinated allyl groups is locally disordered, which is particularly pronounced for II. © 1998 MAEe Cyrillic signK Hayκa/Interperiodica Publishing.
