title: catena-Poly[bis(tert-butylammonium) [plumbate(II)-tri-mu-iodo] iodide dihydrate].
abstract: The title compound, [(C4H12N)2[PbI3]I.2H2O]n, crystallizes as an organic-inorganic hybrid. The six-coordinate Pb atom lies on a centre of inversion and all the I atoms lie on mirror planes; the two independent cations both lie across mirror planes. The structure contains anionic chains along [100] of fused [PbI3]- units forming face-sharing octahedra. Four cations enclose channels occupied by isolated iodide ions and water molecules of hydration.
