%X The crystal structure of trans-[Co( tacd )2](ClO4)3 has been determined by X-ray diffraction methods and refined to a residual of 0.054 for 2477 independent observed reflections. The crystals are monoclinic, P 21/c, a 18.627(2), b 9.3438(5), c 16.057(2)&#506;, &#946; 119.45(2)&#176;. Two complex cations are located at centres of symmetry and the ligands adopt &#955;,&#948;,chair conformations. Bond lengths from cobalt to nitrogen atoms in the six- membered ring (average 1.995 &#506;) are significantly longer than those only associated with five- membered rings (average 1.961 &#506;).
