It was synthesized in 1970 by reacting neptunium(IV) chloride with K<sub>2</sub>(C<sub>8</sub>H<sub>8</sub>). It is ] to ] and ], and they behave chemically identically: all three compounds are insensitive to water or dilute bases but are sensitive to air, reacting quickly to form oxides, and are only slightly soluble in benzene and ].<ref name=Yoshida750>Yoshida et al., pp. 750–2</ref> |
