6a-Nitro-6-phenyl-6,6a,6b,7,8,9,10,12a-octahydrospiro[chromeno[3,4-a]indolizine-12,3′-indolin]-2′-one
In the title compound, C28H25N3O4, the central pyrrolidine ring adopts adopts an envelope conformation with the N atom as the flap and the piperidine ring adopts a chair conformation. The pendant pyrrolidine ring is almost planar (r.m.s. deviation = 0.008 Å). An intra-molecular C-H⋯O inter-action closes an S(6) ring. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds gener...

In the title compound, C(8)H(6)N(2)O(3), the indol-2-one system is almost planar [maximum deviation = 0.010 (3) Å]. In the crystal structure, inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π contacts between the indole ring systems [centroid-centroid distances = 3.494 (1), 3.731 (1) and 3.736 (1) Å] may further stabilize the structure.

In the title compound, C(14)H(10)N(2)O(2), the dihedral angle between the indole and benzene rings is 61.63 (4)°. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by N-H⋯O hydrogen bonds, generating rings of graph-set motif R(2) (2)(8). The dimers are further connected into a three-dimensional network by O-H⋯O and C-H⋯O hydrogen bonds.
