N-[2-(4-Bromo-phen-yl)-5-methyl-4-oxo-1,3-thia-zolidin-3-yl]pyridine-3-carboxamide

Abstract

In the title compound, C(16)H(14)BrN(3)O(2)S, the atoms of the 1,3-thia-zolidine group, except for the N and the C atoms attached to the bromo-benzene ring, are disordered over two sets of sites with occupancies of 0.605 (13) and 0.395 (13). The benzene and pyridine rings make a dihedral angle of 86.2 (2)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯N and C-H⋯O hydrogen bonds, forming a three-dimensional network. Furthermore, there is a π-π stacking inter-action [centroid-centroid distance = 3.758 (2) Å] between the pyridine and benzene rings.
