Abstract
The structures of [Yb5(dbm)10(OH)5]×2CH2Cl2 and [Er5(dbm)10(OH)5]×6CH2Cl2 (dbm = dibenzoylmethanate) were established. The compounds are crystallized in different space groups P4/n and P21/n correspondingly. Ytterbium complex is isostructural to known [Ln5(dbm)10(OH)5]×2C7H8 (Ln = Er, Yb). Structural type of erbium complex prepared in this work has no analogues amongst similar pentanuclear dibenzoylmethanate complexes. The cavities types of the structures filled by CH2Cl2 molecules are different.
