Abstract
The molecular structure of the two complex ions [Co(tmen)(3)](3+) and [Co(tmen)(3)](2+) (tmen=2,3-dimethylbutane-2,3-diamine) have been dete rmined at 100 K. They show a strong trigonal distortion of the octahed ral CoN6 core. The twist angle is 26.2(2.8)degrees for Co-II and 43.9( 9)degrees for Co-III. Average Co-N distances are 2.193(13) Angstrom (C o-II) and 1.997(2) Angstrom (Co-III), 0.02 Angstrom longer than for th e main body of Co-III amines.
