The following compound, ((CH{sub 3}){sub 4}N)(Cl(dmgBF{sub 2}){sub 2}py), where py = C{sub 5}H{sub 5}N and (dmgBF{sub 2}){sub 2}{sup 2{minus}} = bis((difluoroboryl)dimethyl-glyoximato), was crystallized and its molecular structure determined by X-ray diffraction. The distances between Co(I) and the nitrogen of the macrocycle are unusually short (1.839 {angstrom}), even shorter than the corresponding bond (1.878 {angstrom}) in the cobalt(II) analogue. The cobalt atom is displaced 0.257 {angstrom} above the axial plane toward pyridine. Reasons for this unusual Co-N bond shortening are discussed along with the electronic structure of the d{sup 8} cobalt(I) anion.
