4,4'-Bipyridinium bis(perchlorate)-4-aminobenzoic acid-4,4'-bipyridine-water (1/4/2/2).

ABSTRACT: In the structure of the title compound, C(10)H(10)N(2) (2+)·2ClO(4) (-)·4C(7)H(7)NO(2)·2C(10)H(8)N(2)·2H(2)O, the 4,4'-bipyridinium cation has a crystallographically imposed centre of symmetry. The cation is linked by N-H?N hydrogen bonds to adjacent 4,4'-bipyridine mol-ecules, which in turn inter-act via O-H?N hydrogen bonds with 4-amino-benzoic acid mol-ecules, forming chains running parallel to [30]. The chains are further connected into a three-dimensional network by N-H?O and O-H?O hydrogen-bonding inter-actions involving the perchlorate anion, the water mol-ecules and the 4-amino-benzoic acid mol-ecules. In addition, ?-? stacking inter-actions with centroid-centroid distances ranging from 3.663?(6) to 3.695?(6)?Å are present. The O atoms of the perchlorate anion are disordered over two sets of positions, with refined site occupancies of 0.724?(9) and 0.276?(9).
