Sign in to saveAlso known as PbH4, lead hydride, lead(IV) hydride
Plumbane is an inorganic chemical compound with the chemical formula PbH. It is a colorless gas. It is a metal hydride and group 14 hydride composed of lead and hydrogen. Plumbane is not well characterized or well known, and it is thermodynamically unstable with respect to the loss of a hydrogen atom. Derivatives of plumbane include lead tetrachloride, PbCl, and tetraethyllead, (CHCH)Pb.

Plumbane is an inorganic chemical compound with the chemical formula PbH. It is a colorless gas. It is a metal hydride and group 14 hydride composed of lead and hydrogen. Plumbane is not well characterized or well known, and it is thermodynamically unstable with respect to the loss of a hydrogen atom. Derivatives of plumbane include lead tetrachloride, PbCl, and tetraethyllead, (CHCH)Pb.
==History== Until recently, it was uncertain whether plumbane had ever actually been synthesized, although the first reports date back to the 1920s and in 1963, Saalfeld and Svec reported the observation of by mass spectrometry. Plumbane has repeatedly been the subject of Dirac–Hartree–Fock relativistic calculation studies, which investigate the stabilities, geometries, and relative energies of hydrides of the formula MH or MH.
