2-Trifluoromethyl-1H-benzimidazole
نویسنده
چکیده
The asymmetric unit of the title compound, C(8)H(5)F(3)N(2), consists of two half-mol-ecules, one lies on a mirror plane and the other is generated by twofold rotation symmetry, with the axis running through the trifluoro-methyl C atom and the attached benzimidazole C atom. The two 2-trifluoro-methyl-1H-benzimidazole mol-ecules are connected by N-H⋯N hydrogen bonds involving the disordered NH H atoms into chains running parallel to the c axis. One of the trifluoro-methyl groups is disordered over two orientations of equal occupancy.

In the title salt, C(8)H(6)F(3)N(2) (+)·ClO(4) (-), the atoms of the benzimidazole ring (including H atoms) are nearly coplanar (r.m.s. deviation of the fitted atoms = 0.0122 Å) and the triflouromethyl group lies out of this plane. The perchlorate anion adopts a distorted tetra-hedral conformation with the Cl-O bond distances ranging from 1.412 (3) to 1.439 (2) Å. The benzimidazolium cations ar...
