Na2PtI6O18

Na2PtI6O18 is an inorganic compound combining sodium, platinum, iodine, and oxygen—a mixed-valence oxide-iodide that falls into the semiconductor category. This is a research-phase material rather than an established industrial compound; it represents an experimental composition within the broader family of platinum-based mixed-halide and oxide semiconductors. Interest in such materials typically stems from their potential in photocatalysis, ion transport, or optoelectronic applications where the platinum d-orbitals and iodide–oxide framework can mediate charge transfer or light absorption.
