12. 2)4HEDTA.3 A unit weight was assigned to each compound in computing the average: G. H. Cohen and J. L. Hoard, J. Amer. Chem. Soc, 88, 3228 (1966) [DCTA is for trans-1, 2-diami-nocyclohexane-Ar, N'-tetraacetate];

16. Notice that the ruffling will occrr even if the coniplexing bond lengths are of the exact length for a perfect planar ring, since the disposition of the two pairs of hydrogen atoms attached to the carbon atoms is moee favorable when the ring is puckered.

Uchtman, Abstracts, 162nd Nationll Meeting of the American Chemical Society, No. INOR 58, Washington, D. C, 1971). The complex was described as a sexadentate, diaquo, eight-coordinate, species.
