Protactinium(V) chloride

Protactinium(V) chloride is the chemical compound composed of protactinium and chlorine with the formula PaCl5. It forms yellow monoclinic crystals and has a unique structure composed of chains of 7 coordinate pentagonal bipyramids which share their edges.R. P. Dodge, G. S. Smith, Q. Johnson, R. E. Elson: „The Crystal Structure of Protactinium Pentachloride“, Acta Crystallogr., 1967, 22, 85–89; .

Protactinium(V) chloride can react with boron tribromide at high temperatures to form protactinium(V) bromide.Georg Brauer (Hrsg.), unter Mitarbeit von Marianne Baudler u. a.: Handbuch der Präparativen Anorganischen Chemie. 3., umgearbeitete Auflage. Band I, Ferdinand Enke, Stuttgart 1975, ISBN 3-432-02328-6, S. 1177. It also reacts with fluorine to form protactinium(V) fluoride at high temperatures.
