2-Methyl-N-p-tolylbenzamide: a second monoclinic polymorph

A. Saeed, R. A. Khera and J. Simpson

Abstract: The title compound, C₁₅H₁₅NO, (I), is a polymorph of the structure (II) reported by Gowda et al. [Acta Cryst. (2008), E64, o1494]. Compound (II) crystalllizes in the space group C2/c (Z = 8), whereas the title compound occurs in space group P2₁/c (Z = 4). The two molecular structures differ slightly in the relative orientations of their central amide group with respect to the benzoyl ring [dihedral angles of 55.99 (7) for (I) and 59.96 (11)° for (II)] and in the inclination of the benzoyl and aniline rings [88.67 (8) for (I) and 81.44 (5)° for (II)]. In the crystal structure of (I), molecules are linked by N-HO hydrogen bonds, forming C(4) chains, which are augmented by weak C-HO interactions. The structure is further stabilized by C-H contacts involving both of the aromatic rings.
