Wynter, Clive I. published the artcileMoessbauer effect of iodine-129 in pyridine complexes of iodine monohalides, Safety of Pyridine Iodochloride complex, the publication is Journal of Chemical Physics (1969), 50(9), 3872-4, database is CAplus.
The values of isomer shift and quadrupole interaction at the 129I nucleus in IBr and ICl complexes with cyclic N bases have been measured. These have been used to estimate σ and π bondings in these complexes. All these complexes exhibit a linear N-I-X (X = Cl, Br) linkage. Although the Br complexes show a systematic dependence of the isomer shift on the basicity of the complexing cyclic amines, no such trend is observed in Cl complexes.
