# Bis(acetylacetonato)iron(II)

Bis(acetylacetonato)iron(II) is a coordination complex of iron with the formula $Fe(C_5H_7O_2)_2.$ It can be prepared by reacting iron(II) chloride with 2,4-pentanedione in presence of piperidine.

## Reactions

Bis(acetylacetonato)iron(II) reacts with lithium bis(hydropentalenyl)iron to afford green $[(C_8H_7)Fe]_2-[(C_8H_8)_2Fe],$ a quadruple-decker complex.

It reacts with $Li_2Pn^*(TMEDA)_x$ $(Pn^*$ = permethylpentalene) to yield purple-black $Fe_2Pn^*_2.$
