Bis(2-trifluoro-methyl-1H-benzimidazol-3-ium) tetra-chloridomercurate dihydrate.

ABSTRACT: In the title compound, (C(8)H(6)F(3)N(2))(2)[HgCl(4)]·2H(2)O, the Hg(II) cation is coordinated by four Cl(-) anions in a distorted tetra-hedral geometry. In the crystal, the 2-trifluoro-methyl-1H-benzimidazolium cations link to the [HgCl(4)](2-) complex anions and lattice water mol-ecules via N-H?Cl and N-H?O hydrogen bonds, and the lattice water mol-ecules further link to the Hg complex anion and the organic cations via O-H?Cl and O-H?F hydrogen bonding. One of the trifluoro-methyl groups is disordered over two orientations in a 0.59?(4):0.41?(4) ratio.

Bis(2-trifluoro-methyl-1H-benzimidazol-3-ium) naphthalene-1,5-disulfonate.

Project description:The asymmetric unit of the title compound, C(8)H(6)F(3)N(2) (+)·0.5C(10)H(6)O(6)S(2) (2-), consists of one 2-trifluoro-methyl-1H-benz-imidazol-3-ium cation and a half naphthalene-1,5-disulfate anion, which are linked by an N-H?O hydrogen bond. The anion sits across a centre of symmetry. The atoms of the benzimidazole ring are nearly coplanar (r.m.s. deviation of the fitted atoms = 0.0085?Å) and the triflouromethyl group lies out of this plane. In the crystal, the cations are linked to adjacent anions by N-H?O hydrogen bonds, forming a ladder structure parallel to the a axis in which the anions form the rungs. Adjacent ladders are linked by weak C-H?O inter-actions, forming sheets parallel to the ac plane.

2-Trifluoro-methyl-1H-benzimidazol-3-ium tetra-fluoro-borate-2-trifluoro-methyl-1H-benzimidazole-water (1/1/1).

Project description:The asymmetric unit of the title compound, C(8)H(6)F(3)N(2) (+)·BF(4) (-)·C(8)H(5)F(3)N(2)·H(2)O, consists of two 2-trifluoro-methyl-benzimidazole mol-ecules, each of which is protonated on a 50% basis, one tetra-fluoro-borate anion and a water mol-ecule. The two 2-trifluoromethylbenzimidazole mol-ecules thus exist as half-neutral half-cation entities. They are linked by N-H?N hydrogen bonds involving the half-occupancy hydrogens in each mol-ecule. The F atoms of one of the trifluoro-methyl groups are disordered over two sets of sites [in a 0.518?(14):0.482?(14) ratio], as are the F atoms of the tetra-fluoroborate anion [0.507?(14):0.493?(14) ratio]. The water mol-ecule is linked to one of the 2-trifluoro-methyl-benzimidazole mol-ecules via an N-H?O hydrogen bond.
