Crystal structure of diethyl 2,2'-[((1E,1'E)-{[(1R,4R)-cyclo-hexane-1,4-di-yl]bis-(aza-nylyl-idene)}bis-(methanylyl-idene))bis-(1H-pyrrole-2,1-di-yl)]di-acetate.

The whole mol-ecule of the title compound, C24H32N4O4, is generated by inversion symmetry. The cyclo-hexane ring adopts a chair conformation and the conformation about the C=N bonds is E. The pyrrole rings have an anti confirmation with respect to the cyclo-hexane moiety and the ethyl acetate groups have extended conformations. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds forming chains, enclosing R 2 (2)(10) ring motifs with inversion symmetry, propagating parallel to the (101) plane.
