| pubmed-article:22058768 | pubmed:abstractText | In the crystal structure of the title compound, C(11)H(9)ClN(4)O(3), pairs of N-H?N(imidazole) hydrogen bonds connect the mol-ecules into centrosymmetric dimers, which are further connected by N-H?O(carbamo-yl) hydrogen bonds into C(4) chains along [010]. Inter-play of these two kinds of hydrogen bonds connect the mol-ecules into layers perpendicular to [101]. The imidazole [maximum deviation 0.0069?(9)?Å] and phenyl rings are inclined at a dihedral angle of 58.44?(6)°; the nitro group is almost coplanar [dihedral angle 5.8?(2)°] with the imidazole ring while the carbamoyl group is almost perpendicular [70.15?(13)°] to it. | lld:pubmed |
