Popis:	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 determined at 100 K. They show a strong trigonal distortion of the octahedral CoN6 core. The twist angle is 26.2(2.8)° for CoII and 43.9(9)° for CoIII. Average CoN distances are 2.193(13) A (CoII) and 1.997(2) A (CoIII), 0.02 A longer than for the main body of CoIII amines.
