    Abstract:
    Crystals of the title compound are orthorhombic, space group Pnma, with a = 13.182(12), b = 9.115(6), c = 12.132(7) Å, Z = 4. The structure was solved by the heavy-atom method and refined by full-matrix least-squares calculations to R 0.039 for 1070 independent reflexions collected on an automatic diffractometer. The molecule has Cs symmetry with distorted octahedral co-ordination around the cobalt atom; mean equatorial distances: Co-N 1.890(3) Å; axial lengths: Co-O(H2O) 2.058(3), Co-C(sp3) 1.990(5) Å. The intramolecular hydrogen-bonded bridge [O ⋯ O 2.486(4) Å] is not symmetrical. Comparison of the Co-C(sp3) axial bond lengths in like complexes is made and shows that there is no clear evidence for a cis-influence with variation in equatorial ligand.
