Abstract

In the title compound, C(26)H(28)INO(4)·H(2)O, benzene rings are inclined at a dihedral angle of 69.9 (1)°. The N-containing ring exhibits a chair conformation, while the other rings approximate to envelope conformations. In the crystal, the uncoordinated water mol-ecule forms inter-molecular O-H⋯O and O-H⋯N hydrogen bonds.
