Di-tert-butyl N,N'-(octa-hydro-penta-lene-2,5-di-yl)dicarbamate.

ABSTRACT: In the molecule of the title compound, C(18)H(32)N(2)O(4), the central bicyclo-[3.3.0]octane (octa-hydro-penta-lene) has a rigid ring junction. Both rings of the bicyclo-[3.3.0]octane unit adopt an envelope conformation, and the flexible tert-butyl-carbamoyl side chains each have an extended conformation. Such a constrained bicyclo-[3.3.0]octane aliphatic template is of inter-est with respect to the design of novel self-assembling motifs. Mol-ecules related by c-glide symmetry are linked via inter-molecular N-H?O hydrogen bonds, forming a two-dimensional layer structure. Neighboring layers are weakly associated along the a axis due to the close approach of the tert-butyl-carbamoyl groups (2.55?Å).
