'''四氟化锎'''是[[锎]]的一种[[氟化物]]，[[化学式]] CfF<sub>4</sub>，其中锎的氧化态为+4。

== 制备==
四氟化锎可以由[[三氧化二锎]] Cf<sub>2</sub>O<sub>3</sub> 和[[氟气]]在 400&nbsp;°C 下反应而成：<ref name="dictic">J. E. Macintyre, F. M. Daniel, V. M. Stirling: ''Dictionary of inorganic compounds'', Chapman and Hall, CRC Press, 1992, ISBN 978-0-412-30120-9, S.&nbsp;2826.</ref>

: <chem>2\ Cf_2O_3\ +\ 8\ F_2\ \xrightarrow{400\ ^\circ C} \ 4\ CfF_4\ +\ 3\ O_2</chem>

它也可以由[[四氟化锫]]-249 (<sup>249</sup>BkF<sub>4</sub>)的[[β衰变]]而成。<ref name="dictic" />

== 性质==
四氟化锎是一种[[离子化合物]]，由 Cf<sup>4+</sup>和 F<sup>−</sup>组成。它是[[单斜晶系]]的，[[空间群]] C2/c (No. 15)。它的晶体结构和[[四氟化铀]]一样。<ref>L. B. Asprey, R. G.
