Abstract top

The title compound, C26H29N3O2, crystallizes with two molecules in the asymmetric unit, having C-H...O interactions between them and resulting in a dimer characterized by an R22(11) motif. These dimers are linked into an ABABAB chain via N-H...O, N-H...N and C-H...O built edge-fused R12(5) and R22(7) motifs. This chain is linked to its inversion-related partner via N-H...O bonds with an R22(8) motif and leads to a double chain extending along the b axis characterized by an R66(36) motif across the inversion centres. The methyl group of the phenyl ring and the oxindole of molecule A and B are involved in C-H...[pi] interactions. One C atom of the pyrrolizine ring of molecule A and its attached H atoms show positional disorder, the major and minor components being in the ratio 0.706 (7):0.294 (7).

Comment top

The title compound contains two molecules in the asymmetric unit forming an asymmetric dimer through C—H···O hydrogen bonds between them. The molecular structure with displacement ellipsoids drawn at 50% probability level is shown in Fig.1. The C8—O1 distance in the indolone in molecules A and B are 1.2244 (18)and 1.215 (2) A°, respectively. The difference in the C8—O1 bond distances in molecules A and B is substantiated by the deviation of O1 from the plane by about 0.4122 (18) in molecule A and 0.2907 (21) in molecule B. This deviation of O1 from planarity seems to have considerably influenced differences in the values of the torsion angles N1—C1–C8—O1 and C2—C1—C8—O1 of molecules A and B. In molecule A, these torsion angles are 37.5 (2) and -75.6 (2)° while in B these values are -53.8 (2) and 61.0 (2)°, respectively. These differences in conformation may also be attributed to a significant intermolecular feature that O1A participates in a three-centered hydrogen bond involving N—H···O and N—H···N types and O1B in a C—H···O type hydrogen bond.

The carbon atom C6 in the hexahydropyrrolizine ring of molecule A shows positional disorder with major and minor component of 0.71 and 0.29, respectively for its site occupancy factor. This disorder leads to a flipping of the conformation of the N1—C4—C5—C6—C7 ring with the puckering parameters (Cremer & Pople, 1975) observed as twisted on C5—C6 with q=0.393 Å, φ=271.4 (3)° for the major component and twisted on C6—C7 with q=0.347 (5) Å, φ=125.0 (7) ° for the minor component. The corresponding ring in molecule B shows similar twist conformation but with the twist on N1—C4 with q=0.394 (2) Å, φ=15.9 (4) °. The puckering of the five-membered ring N1—C1—C2—C3—C4 of the pyrrolizine is envelope (3E) on atom C2 with q = 0.3615 (17) Å, φ = 66.3 (3)° in molecule A and envelope (E5) on atom C4 with q = 0.4364 (19) Å, φ = 320.7 (2) ° in molecule B. The puckering of the piperidinone rings in both the molecules is close to the usual chair with Q = 0.551 (2) Å, θ = 24.0 (2)°, φ = 353.7 (8)° for molecule A and Q = 0.559 (2) Å, θ = 16.4 (2)°, φ = 339.4 (8)° for molecule B. The hydrogen-bonded interaction (Table 1) between molecules generate one-dimensional double chains extending along the b axis (Fig.2).

The molecular interaction pattern is characterized by four different graph-set motifs (Bernstein et al., 1995) viz. R22(8), R22(7), R21(5) and a R22(11) type. The R22(11) motif occurs between the two molecules in the asymmetric unit through C—H···O hydrogen bonds. The R22(8) is built across inversion centres through N—H···O hydrogen bonds. R22(7) is edge fused with a R21(6) motif, in which the N—H···N bond is the shared edge, while C—H···O and N—H···O, respectively are their respective characteristic units. An interesting feature is that all these fundamental simple graph-set motifs lead to a complex R66(36) motif across the inversion centres. Also two significant C—H···π viz. C6A—H63A···Cg1(C20A→C25A) and C6B—H62B···Cg2 (C20B→C25B) interactions are observed. Thus, the presence of a variety of interaction patterns in the crystal structure of a geometrically unfathomable molecule may well be regarded significant in the context of crystal structure prediction.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
