Abstract
By reaction of triphenylamylphosphonium iodide [Ph3AmP]I (I) with antimony iodide in acetone, triphenylamylphosphonium tetraiodide [Ph3AmP]2I4 (II) was synthesized. Crystals of I consist of triphenylamylphosphonium cations and iodine anions. Compound II contains two types of tetrahedral triphenylamylphosphonium cations, iodine anions, and [I3]− anions. Atoms P have a distorted tetrahedral coordination in cations I and II (the CPC angles are 106.48(12)°–111.25(12)° in I and 107.05(9)°–112.62(10)° in II). The centrosymmetric trinuclear [I3]− anion in II is nearly linear (the I(2)I(1)I(3) angle is 178.65°, the I(1)–I(2) and I(1)–I(3) bond lengths are 2.8925(2) Å and 2.9281(2) Å, respectively).
