Abstract
The analysis of crystal structures of the series of ammine-nitro cobal t(III) complexes has shown that Co-NO2 bond lengths can be successfull y rationalized on the basis of the anisotropic pi-effect of nitro grou ps. This effect governs both the orientation of the nitro group and th e Co-NO2 length, and explains the irregularities in the increase of th e latter with the increasing number of NO2 groups present in the coord ination sphere.
