Compositions of matter and methods of preparation are described for water and air stable, square planar transition metal double-complex salts which contain isonitrile ligands derivatized with long chain aliphatic groups. These salts are composed of two metal-containing complex ions: the cation is a tetrakis isonitrile metal ion and the anion is a tetrahalometallate or tetracyanometallate. These double-complex salts exhibit the novel property of thermochromism and are useful as temperature indicators and in imaging applications.
