Caesium phosphide refers to any of several inorganic compounds with the formula CsPx. The most studied member is Cs3P7,[1] which forms yellow crystals of tetragonal structure (P41 group),[2] which turn brown when heated to 300 °C, and colorless when cooled with liquid nitrogen.

Structure of the P73- subunit as found in Cs3P7.

Other cesium phosphides

CsP15 is also claimed.[3] Cs4P6 is a layered compound consisting of planar P64- rings.[4]
