Di-tert-butylphosphate complexes of Mn(II) and Cu(II) as single-source precursors for metal phosphate materials

Abstract

Octahedral Mn(II) and Cu(II) di-tert-butylphosphate (L) complexes [ML2(imz)4] have been synthesized and characterized using IR, UV-vis, luminescence, and EPR spectroscopy and single crystal X-ray diffraction studies. Thermal decomposition of both the complexes (probed by TGA, DTA, and DSC) indicate stepwise elimination of iso-butene, imidazole and water to finally yield the respective ceramic materials Mn(PO3)2 or Cu(PO3)2.
