Urea (12 g, 0.2M), Succinimide (19.8 g, 0.2M) and Benzaldehyde (22 ml, 0.2M) were taken in equimolar ratio. A concentrated aqueous solution of urea and succinimide was prepared. Benzaldehyde was added in drops with continuous stirring of the solution. The mixture first became oily and then slowly turned into a white crystalline mass, which was separated by suction filtration and washed several times with water. The product was dried and recrystallized using acetone by slow evaporation (Tramontini, 1973; Tramontini & Angliolini, 1990).
All the H atoms except those of N atoms were geometrically fixed at chemically meaningful positions. The hydrogen atoms of the phenyl ring were allowed to ride at a distance of 0.93 Å from the parent carbons and their thermal parameter were fixed at 1.2 times that of the parent atom. The secondary CH2 hydrogen were fixed at a distance of 0.97 Å from the parent atom and their thermal parameters were fixed at 1.2 times the parent atom. The H atoms associated with nitrogen atoms were located from the difference fourier map and refined. However, their distances were constrained from the parent atom to avoid abnormal geometry.
Mannich bases- compounds with the general formula R—CH2—N< have been studied extensively, because of their applications in pharmaceutical and polymer chemistry. They are very good model systems for both intermolecular and intramolecular hydrogen bonding and a variety of other effects (Wozniak et al., 2000). In the crystal structure of the title compound, the molecules which are related through center of inversion are linked to each other through N3—H3···O3 hydrogen bonds (2.363 (11) Å, 155.1 (15) °). They form a dimeric pair. These dimeric pairs are linked to its b-translation equivalent through N2—H2···O2 (2.19 Å, 149.4 °) hydrogen bonding. The hydrogen bonded dimer and the translation equivalents form an one dimensional dimeric chain running parallel to the b axis. The one dimensional chains are linked through van der Waals interactions. Succinimide moiety is almost planar with maximum deviation of 0.032 Å for the N atom from the least squares mean plane of atoms. The planarity can be attributed to the sp2 hybridization of C1 and C4 atoms.

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. |

Mannich bases- compounds with the general formula R—CH2—N< have been studied extensively, because of their applications in pharmaceutical and polymer chemistry. They are very good model systems for both intermolecular and intramolecular hydrogen bonding and a variety of other effects (Wozniak et al., 2000). In the crystal structure of the title compound, the molecules which are related through center of inversion are linked to each other through N3—H3···O3 hydrogen bonds (2.363 (11) Å, 155.1 (15) °). They form a dimeric pair. These dimeric pairs are linked to its b-translation equivalent through N2—H2···O2 (2.19 Å, 149.4 °) hydrogen bonding. The hydrogen bonded dimer and the translation equivalents form an one dimensional dimeric chain running parallel to the b axis. The one dimensional chains are linked through van der Waals interactions. Succinimide moiety is almost planar with maximum deviation of 0.032 Å for the N atom from the least squares mean plane of atoms. The planarity can be attributed to the sp2 hybridization of C1 and C4 atoms.
