Tungsten dioxide is the chemical compound with the formula WO2. The bronze-colored solid crystallizes in a monoclinic cell. The rutile-like structure features distorted octahedral WO6 centers with alternate short W–W bonds (248pm). Each tungsten center has the d2 configuration, which gives the material a high electrical conductivity.
