Crystal structure of <i>trans</i> -chlorobis(ethane-l,2-diamine)sulfitocobalt(III) monohydrate

Abstract

The crystal structure of the title compound, [Co(en)2ClSO3],H2O (en = ethane-1,2-diamine), has been determined by single-crystal X-ray diffraction methods at 295(1) K and refined by least squares to a residual of 0.050 for 3252 'observed' reflections. Crystals are monoclinic, P21/c, a 9.862(4), b 15.897(8), c 16.936(7) ?, ß 117.44(4)°, Z 8. The two independent molecules in the asymmetric unit are pseudosymmetrically related. (Co-S) is 2.204 ?, while (Co-Cl) is the longest six-coordinate cobalt(III)-chloride distance observed, being 2.377 ?.
