Properties
Plutonium selenide forms black crystals of a cubic system, space group Fm{{overline|3}}m, cell parameters a = 0.57934 nm, Z = 4, structure of the NaCl type.{{cite journal |last1=Gensini |first1=M. |last2=Gering |first2=E. |last3=Heathman |first3=S. |last4=Benedict |first4=U. |last5=Spirlet |first5=J.

With increasing pressure, two phase transitions occur: at 20 GPa into the trigonal system and at 35 GPa into the cubic system, a structure of the CsCl type.
Its magnetic susceptibility follows the Curie-Weiss law.{{cite book |last1=Macintyre |first1=Jane E. |title=Dictionary of Inorganic Compounds |date=23 July 1992 |publisher=CRC Press |isbn=978-0-412-30120-9 |page=3783 |url=https://books.google.com/books?id=9eJvoNCSCRMC&q=plutonium+selenide&pg=PA3783 |access-date=6 August 2021 |language=en}}
