Die Kristallstruktur eines 1:2-Chrom(III)-Komplexes vom Sandwichtypus

The crystal structure of the triclinic modification of the 1:2 complex of chromium-(III) with the azo dye from 3-methyl-anthranilic acid with 1-(4-bromophenyl)-3-methyl-5-pyrazolone has been determined. The space group is P1 with a = 13,46 Å, b = 14,79 Å, c = 12,56 Å, α = 62°30′, β = 106°51′ and γ = 98°25′. The structure was solved by the heavy atom technique and refined by blockdiagonal least squares method. The sandwich configuration postulated by SCHETTY 1] was confirmed.
