· NiI

NiI is a nickel iodide compound that exists primarily as a research material rather than a commercial engineering alloy. This intermetallic or coordination compound belongs to the nickel halide family and has been investigated for potential applications in catalysis, electrochemistry, and solid-state chemistry. While not widely deployed in conventional structural applications, nickel iodide compounds are of interest in emerging technologies where nickel's catalytic properties and iodine's electrochemical reactivity can be leveraged.
