چکیده
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 C-ethyl-2-methylresorcinarene (1) forms 1:1 in-cavity complexes with aromatic N,N'-dioxides, only if each of the aromatic rings has an N-O group. The structurally different C-shaped 2,2'-bipyridine N,N'-dioxide (2,2'-BiPyNO) and the linear rod-shaped 4,4'-bipyridine N,N'-dioxide (4,4'-BiPyNO) both form 1:1 in-cavity complexes with the host resorcinarene in C4v crown and C2v conformations, r...
