sup 127 I Moessbauer studies of oxygen-bonded iodine complexes. 1. Tris(carboxylato)iodine(III) derivatives. Crystal and molecular structure of tris(acetato)iodine(III)
- McMaster Univ., Hamilton, Ontario (Canada)
{sup 127}I Moessbauer spectra have been recorded at 4.2 K for a series of tris(carboxylato)iodine(III) derivatives. The observed Moessbauer parameters appear to be influenced only by the primary bonds to iodine. Details of the preparation of a Mg{sub 3}{sup 127m}TeO{sub 6} source for {sup 127}I Moessbauer spectroscopy are given. The crystal and molecular structure of tris(acetato)iodine(III). I(O{sub 2}CCH{sub 3}){sub 3}, has been determined. The crystals are monoclinic, of space group P2{sub 1}/c, with a = 6.630 (1) {angstrom}, b = 8.047 (3) {angstrom}, c = 18.296 (4) {angstrom}, {beta} = 93.82 (2){degree}, V = 974 (1) {angstrom}{sup 3}, D{sub c} = 2.07 g cm{sup {minus}3} for Z = 4, and R{sub 1} = 0.0863 (R{sub 2} = 0.0982) for 1436 reflections. The geometry about iodine consists of primary bonds to the three acetate groups (I-O = 2.159 (12), 2.023 (15), 2.168 (12) {angstrom}) and two strong intramolecular secondary bonds (I---O = 2.463 (13), 2.518 (13) {angstrom}) to two of the acetate groups forming a AX{sub 3}Y{sub 2}E{sub 2} pentagonal-planar arrangement. 29 refs., 3 figs., 5 tabs.
