Dipentyl 2,6-diaminobenzo[1,2-b :4,5-b ]difuran-3,7-dicarboxylate

In the title compound, C22H28N2O6, the molecule is located on an inversion centre with penthyl groups in the all-trans conformation. Intramolecular hydrogen bonding involving the amino group and ester carbonyl helps to lock the syn conformation of the ester with respect to the amino group. Intermolecular N-H•••O hydrogen bonding self-assembles the molecules into a two-dimensional hydrogen-bonded network parallel to (010) that displays interdigital packing sustained by alkyl–alkyl interactions.
