Bis(μ-ferrocene­carboxyl­ato)bis­[aqua­­bis(ferrocene­carboxyl­ato)methano­l­erbium(III)] methanol disolvate

In the centrosymmetric title coordination compound, [Er(2){Fe(C(5)H(5))(C(6)H(4)O(2))}(6)(CH(3)OH)(2)(H(2)O)(2)]·2CH(3)OH, the two Er(III) ions are bridged by two ferrocene­carboxyl­ate anions as asymmetrically bridging ligands, leading to dimeric cores. The Er(III) 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.
