Hydrid cesný je anorganická sloučenina cesia s vodíkem se vzorcem CsH, která má iontovou strukturu Cs+ H.

Vlastnosti

Hydrid cesný je neobyčejně reaktivní, vzplane až vybuchuje na vlhkém vzduchu:

Reaguje s halogeny za vzniku halogenidů cesných (a halogenvodíkových kyselin):

se sirouhlíkem:

Při zahřátí reaguje i s dusíkem, amoniakem a fosforem.

Příprava

Je první sloučeninou, která byla připravena za pomoci laserovým světlem indukovaného formování částic ve výparech alkalického kovu.[2] Může být připraven také přímou vzájemnou reakcí výchozích prvků při teplotě 200–350 °C za tlaku 5–10 MPa:
