✦ Synopsis

Ž

. A new synthetic route to isothiocyanate containing materials is presented. Five isothiocyanate 4-methylpyridine ␥-picoline Ž . compounds were prepared by refluxing metal powders Fe, Co, Ni and Cu with thiourea in ␥-picoline. The isothiocyanate ligand q y w Ž . Ž . x is generated in situ by the isomerization of thiourea to NH SCN at reflux temperatures. The complexes Fe NCS pic и pic 4 2 4 Ž . w Ž . Ž . x Ž . w Ž . Ž . x Ž . w Ž . Ž . x Ž . w Ž .Ž . x Ž .
