Protactinium trihydride

Compact (bulk) plutonium hydride (Puj s to PuH2,65) has been obtained by hydriding under pressure a-Pu in the plastic range (350-400 °C). Protactinium trihydride is less stable than uranium trihydride ... 

Protactinium metal reacts with hydrogen to form the black hydride, PaHj, which is isostructural with other actinide trihydrides it has only been prepared in submilligram amounts and identified by X-ray powder diffraction analysis (125).
