Crystallographic and spectroscopic studies of adducts of indium (III) iodide with two cyclic ketones

This is the authors' abstract. We don't add key points for this paper.

Indium(III) iodide forms a 1:1 adduct with 9-xanthenone, of quasi-tetrahedral structure; triclinic, a = 10.805(4), b = 11.494(4), c = 7.493 (2) Å , α = 104.12(3), β = 106.35(3), γ = 91.165(3)°, V = 860.8(5) Å 3 , Z = 2, space group P1 - . With 9-fluorenone, the adduct has 1:2 stoichiometry, and approximately D 3h symmetry in the InI 3 O 2 kernel; the structure is triclinic, a =11.212(2), b = 16.504(3), c = 7.537(2) Å, α = 94.57(2), β = 109.05(1), γ = 91.165(15)°, V = 1312.6(4) Å 3 , Z = 2, space group P1 - . The solid structures, and the solution chemistry, are compared with those of related neutral derivatives of indium(III) halides.
