A multicyclic molecule (illustrated here) was prepared by self‐assembly of 1,3,5‐pentanetriamine and formaldehyde in quantitative yield. This molecule can exist in four diamond‐lattice conformations of symmetries D 2d , S 4 , C 2v and D 2d . A conformation interconversion scheme is proposed. It involves also two less populated quasi‐diamond‐lattice intermediates; one of which forms a clathrate with dioxane.
