5-Amino-2,4,6-triiodo-isophthalic acid-4,4'-bipyridine N,N'-dioxide-water (1/1/1).

ABSTRACT: The aromatic rings of the N,N'-dioxide molecule in the title compound, C(8)H(4)NI(3)O(4)·C(10)H(8)N(2)O(2)·H(2)O, are twisted by 14.0?(2)°. The -CO(2)H substituents of the 5-amino-2,4,6-triiodo-isophthalic acid are twisted by 83.0?(2) and 86.5?(2)° out of the plane of the aromatic ring. In the crystal, the three components are linked by O-H?O hydrogen bonds into a three-dimensional network. An N-H?O inter-action also occurs. One of the amino H atom is not involved in hydrogen bonding.

The aromatic rings of the N,N'-dioxide molecule in the title compound, C(8)H(4)NI(3)O(4)·C(10)H(8)N(2)O(2)·H(2)O, are twisted by 14.0 (2)°. The -CO(2)H substituents of the 5-amino-2,4,6-triiodo-isophthalic acid are twisted by 83.0 (2) and 86.5 (2)° out of the plane of the aromatic ring. In the crystal, the three components are linked by O-H⋯O hydrogen bonds into a three-dimensional network. An N-H⋯O inter-action also occurs. One of the amino H atom is not involved in hydrogen bonding. ...[more]
