Abstract
The crystal structure of (−)589-[Co acac tn2][As-(+)-tart]2·H2O has been determined by the X-ray diffraction method. The crystals are monoclinic, with lattice constants of a=12.02(1) Å, b=13.73(2) Å, c=9.02(1) Å, and β=107.4(3)°, and with the space group of P21, containing two formula units in a cell. The structure was determined by the application of Patterson and Fourier techniques and was refined by the least-squares method to an R factor of 10.4%. The absolute configuration of (−)589-[Co acac tn2]2+ can be denoted as Δ. The two Co-tn chelate rings assume the chair form, and the Co-acac chelate ring is almost planar. The geometry of [As-(+)-tart]22− is identical with that of [Sb-(+)-tart]22−.Keywords
