Abstract The crystal structure of (+)589-[Co(CN)2en2]Cl·H2O has been determined from three-dimensional X-ray photographic data. The crystals are monoclinic, with the lattice constants of a=8.15(1), b=11.69(2), c=6.61(1) Å, and β=107.1(2)°, and with the space group of P21 containing two formula units in the cell. The structure was solved by a conventional Fourier technique and was refined by the least-squares method to an R factor of 0.114. The absolute configuration of the complex ion can be denoted as Λ(λλ); this is in accordance with the assignment made by Mason et al. The complex ion has an approximately two-fold axis, and both of the ethylenediamine chelate rings are of the ob-conformation.
