The structure of Δ-(8-methyl-1,3,6,10,13,16,19-heptaazabicyclo[6.6.6]icosane)cobalt(III) perchlorate monohydrate, Δ-[Co(C14H33N7)](ClO4)3·H2O, has been determined by single crystal X-ray diffraction techniques. Crystal data are the following: space group P212121, a=16.379(2) Å, b=16.388(2) Å, c=9.753(1) Å, V=2617.9(5) Å3, Z=4, 3983 nonzero structure factors (|Fo|>3σ(|Fo|)), R=0.0447, and Rw=0.0491. The geometry of the cation can be approximated very closely by a composite of [Co(sen)]3+ and [Co(sep)]3+, where sen=1,1,1-tris(4-amino-2-azabutyl)ethane and sep=1,3,6,8,10,13,16,19-octaazabicyclo[6.6.6]icosane.
