The crystal structure of (+)(589)-Dichlorobis(ethylenediamine)-cobalt(III) chloride monohydrate

The crystal structure of cis-(+)(589)- [CoCl(2)en(2)]Cl.H2O has been determined by the X-ray-diffraction method. The crystal is monoclinic with the cell constants: a = 12.07, b = 11.52, c = 8.33 A, and beta = 96.9 degrees. The space group is P2(1), and Z=4. There are two crystallographically-independent complexes in the unit cell, but they have the same configuration and almost identical molecular dimensions. The absolute configuration of the complex cation is consistent with that proposed by McCaffery, Mason and Norman and should be denoted as Lambda(delta delta).
