Zinc phosphide (Zn3P2) is an inorganic chemical compound. It is a grey solid, although commercial samples are often dark or even black. It is used as a rodenticide.[5] Zn3P2 is a II-V semiconductor with a direct band gap of 1.5 eV[6] and may have applications in photovoltaic cells.[7] A second compound exists in the zinc-phosphorus system, zinc diphosphide (ZnP2).
