Spectroscopic Studies and Crystal Structure of 1-[(2,5-dioxopyrrolidin-1-yl)(phenyl) methyl] Thiourea

A new mannich base 1-[(2,5-dioxopyrrolidin-1yl)(phenyl)methyl] thiourea formed by the direct condensation of thiourea, succinimide and benzaldehyde has been synthesized. The structure of this mannich base has been elucidated on the basis of micro elemental analysis, IR, H-1 NMR, C-13 NMR, Mass and UV-Visible Techniques. The crystal structure of the title compound C-12 H-13 N-3 O-2 S was determined. It crystallizes in the monoclinic system, space group P2(1)/c with a = 10.8234 (7) angstrom, b = 6.0355 (5) angstrom, c = 19.3692 (14) angstrom, beta = 100.540(3)degrees, Z = 4 and V = 1243.94 (16) angstrom(3). The structure was solved by the full-matrix least squares on F-2 and had a refined R value of 0.0465 for 1,964 observed reflections. The crystal structure is stabilized by strong intramolecular C-H center dot center dot center dot O, C-H center dot center dot center dot S interactions and inter molecular N-H center dot center dot center dot O and S center dot center dot center dot S interactions.
