22. -3, hydrogens calculated and refined as riding atoms, three chemically identical molecules with different conformation in the asymmetric unit. The anisotropic displacement parameters of molecule A indicate some unrefined positional disorder. Data set was collected with a Nonius KappaCCD diffractometer, equipped with a rotating anode generator. Programs used: data acquisition COLLECT, data reduction DENZO-SMN, absorption correction SORTAV, structure solution SHELXS-86, structure refinement SHELXL-97, graphics DIAMOND.
