The synthesis is simple, the structure very unusual . The [Pb 18 I 44 ] 8− ion (shown on the right), as a fraction of the NaCl structure type, is the largest iodoplumbate with discrete anions reported to date. The anion is obtained in the reaction of PbI 2 with NaI in acetone as the tetrabutylammonium salt in the form of highly refractive, yellow octahedral crystals.
