Tetrakis(μ-propanoato-κ2O:O′)bis[(1,10-phenanthroline-κ2N,N′)(propanoato-κ2O,O′)samarium(III)]

The title complex, [Sm2(C3H5O2)6(C12H8N2)2], is a dinuclear centrosymmetric molecule, in which two crystallographically equivalent Sm atoms, separated by 3.9502 (2) Å, are bridged by four propanoate anions. Each Sm atom is coordinated by two N atoms from one chelating phenanthroline ligand and seven carboxylate O atoms from five propanoate anions, to form a distorted tricapped trigonal prism.
