چکیده

In the two mol-ecules of the asymmetric unit of the title compound, C(12)H(11)N(3)O(4), the seven-membered diazepine ring adopts a boat conformation (with the two phenyl-ene C atoms representing the stern and the methine C atom the prow). The five-membered pyrrole ring, which has an envelope conformation, makes dihedral angles of 60.47 (10) and 54.69 (9)° with the benzene ring of the benzodiazepine unit in the two mol-ecules. In the crystal, inter-molecular N-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.8023 (7)-3.8946 (7) Å] lead to the formation of a three-dimensional framework.

10-Allyl-2,3-dihydro-1H-pyrrolo[2,1-c][1,4]benzodiazepine-5,11(10H,11aH)-dione

The compound, C(15)H(16)N(2)O(2), features a pyrroline ring fused with a seven-membered diazepine ring; the latter system adopts a boat conformation (with the methine C atom as the prow and the two C atoms of the aromatic ring as the stern). A CH(2)-CH(2) segment of the pyrroline ring is disordered over two positions in a 1:1 ratio.

The organic mol-ecule and uncoordinated water mol-ecule in the crystal of the title compound, C(25)H(24)N(4)O(4)·2H(2)O, both lie on special positions of twofold symmetry. A twofold rotation axis passes through the methyl-ene C atom connecting the two dihydro-benzopyrrolodiazepindionyl parts. The seven-membered C(5)N(2) ring adopts a boat conformation.
