Manganocene or bis(cyclopentadienyl)manganese(II) is an organometallic compound of manganese. It is a metallocene.
In the solid state, manganocene adopts a polymeric structure with every manganese atom coordinated by three cyclopentadienyl ligands, two of which are bridging ligands. This compound has an electron count of 17; it is readily reduced to Cp2Mn−, which has an ideal electron count of 18 (see 18-electron rule).[1]
This metallocene is commercially available. It may be prepared in the conventional fashion, by reaction of manganese(II) chloride with sodium cyclopentadienide:
- MnCl2 + 2 CpNa → Cp2 Mn + 2 NaCl
