Abstract:
In the title compound, (C(12)H(11)N(3))[BiCl(5)]·H(2)O, the Bi(III) atom is coordinated by five chloride anions in a distorted square-pyramidal geometry. The planar imidazole ring system [maximum deviation = 0.012 (3) Å] is oriented at a dihedral angle of 6.08 (5)° with respect to the protonated pyridine ring. An O-H⋯Cl inter-action links the water mol-ecule to the dianion. In the crystal structure, inter-molecular O-H⋯Cl, N-H⋯O and N-H⋯Cl inter-actions link the mol-ecules into a three-dimensional network.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
