Abstract The reactions of iso-tellurazole N -oxides with monocations of the coinage metals yielded a family of coordination complexes with a remarkable variety of compositions and structures. All new species were identified by single-crystal X-ray diffraction.
Coinage metals: Coinage metal contains three metallic chemical elements. It is composed of Gold Au, Silver Ag and Copper Cu metals; They are classified as coinage metals since they were used in making coins. Properties of Coinage metals: They are malleable as they can be drawn into thin sheets. They have high thermal/electrical conductivity.
