Thermal transformations and stability of organometallic materials with electrical and optical properties: The case of polycrystalline cis-[Ir(CO)(sub 2)Cl(C(sub 5)H(sub 5)N)]

The solid-state transformations under heating of cis-[Ir(CO)(sub 2)C1(C(sub 5)H(sub 5)N)] are examined by integrating infrared spectroscopy, conventional and bidimensional X-ray diffraction, thermal analysis, and hot stage optical microscopy. The structural changes associated with the solid-state transformations of organometallic compounds can be successfully achieved by integrating different investigation techniques.
