In the centrosymmetric title coordination compound, [Er2{Fe(C5H5)(C6H4O2)}6(CH3OH)2(H2O)2]·2CH3OH, the two ErIII ions are bridged by two ferrocenecarboxylate anions as asymmetrically bridging ligands, leading to dimeric cores. The ErIII ion has a distorted dodecahedral coordination with six coordinating O atoms derived from the ferrocenecarboxylate ligands and two coordinated O atoms from one water molecule and one methanol molecule. The asymmetric unit comprises a half of the complex molecule and a methanol solvent molecule. Intramolecular O—H...O and C—H...O interactions occur. In the crystal, molecules are linked by intermolecular O—H...O hydrogen bonds and C—H...O as well as C—H...π interactions.
