Californium(IV) oxide is a binary
inorganic compound
An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bondsthat is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as ''inorganic chemistry''.

Synthesis
Californium dioxide is produced by oxidizing californium with molecular and atomic oxygen at high pressure.
Physical properties
Californium(IV) oxide is a black-brown solid that has a cubic
fluorite crystal structure
The fluorite structure refers to a common motif for compounds with the formula MX2. The X ions occupy the eight tetrahedral interstitial sites whereas M ions occupy the regular sites of a face-centered cubic (FCC) structure. Many compounds, notabl ...
with a lattice parameter, the distance between unit cells in the crystal, of 531.0 ± 0.2 pm.
