Bis[2-(4-aminophenyl)-4,5-dihydro-1H-imidazol-3-ium] dichloride monohydrate
نویسندگان
چکیده
The asymmetric unit of the title compound, 2C(9)H(12)N(3) (+)·2Cl(-)·H(2)O, comprises two mol-ecules, two chloride anions and one mol-ecule of crystal water. In the imidazolinium ring, the protonation contributes to delocalization of the positive charge over the two C-N bonds. Both chloride anions are acceptors of four hydrogen bonds in a flattened tetra-hedron environment. The donors are NH(2) groups, the NH groups of the imidazolinium rings and the water mol-ecule. These hydrogen bonds and N-H⋯O(H(2)O) hydrogen bonds form a three-dimensional network.
