The crystal and molecular structure of two benzimidazole derivatives: 1-(phenylmethyl)-2-(4-methoxyphenylmethyl)-1H-benzimidazole-5-carboxylic acid (I) and 1,2-di-(phenylmethyl)-1H-benzimidazole-5-carboxylic acid (II)

The crystal structures of C 23H 20N 2O 3 (I) and C 22H 18N 2O 2 (II) have been determined by single-crystal X-ray diffraction. These two compounds crystallise in the monoclinic space groups, P2 1 c and C2 c . The structures have been determined by direct methods and refined to R, 0.041 (I) and 0.070...

Summary:The crystal structures of C 23H 20N 2O 3 (I) and C 22H 18N 2O 2 (II) have been determined by single-crystal X-ray diffraction. These two compounds crystallise in the monoclinic space groups, P2 1 c and C2 c . The structures have been determined by direct methods and refined to R, 0.041 (I) and 0.070 (II). The benzimidazole ring systems in (I) and (II) are planar. The phenyl rings attached to N1 and C2 in (I) are planar and make dihedral angles of 88.5(1) and 103.8(1)° with the benzimidazole ring systems. Corresponding angles in (II) are 95.0(2) and 105.1(2)°.
