Cyclo-hexane-1,3-diyl bis-(N-phenyl-carbamate).

ABSTRACT: The asymmetric unit of the title compound, C(20)H(22)N(2)O(4), comprises two crystallographically independent mol-ecules (A and B) with slightly different geometries. The dihedral angle between the two terminal phenyl rings is 61.7?(1)° in mol-ecule A and 29.6?(1)° in B. The cyclo-hexane rings adopt chair conformations. In the crystal packing, inter-molecular N-H?O hydrogen bonds inter-connect adjacent mol-ecules into a ladder-like structure along the c axis incorporating R(2) (2)(20) ring motifs. The crystal packing is further stabilized by weak inter-molecular C-H?? inter-actions.
