Multimetallic oxides, because of their specific properties may represent an important class of new materials. Unfortunately the high processing temperatures typically applied make them less useful for nanoscaled materials. Because of this to generated bimetalic oxide we use molecular single-source alkoxdie precursors which are suitable for formation of oxides or other materials.

During our investigation of manganese systems, we have found that heterometallic alkoxide precursors are excellent to generate oxide materials. The method allows these oxides to be formed in one step at molecular level. In this communicaion synthesis and crystal structure of alkoxide precursors - [Mn₂Ba₂(OC₆H₄OCH₂CH₃)₈(CH₃OCH₂CH₂OH)₂] (1) will be presented. The thermogravimetric analysis (TGA) investigation with the temperature varied from 25 to 1000°C in steps of 10°C shows that decomposition of 1 is noticeable at about 400 ^oC in dinitrogen. The properties of the resulting oxide: BaMnO₃ were characterized by powder X‑ray diffraction spectroscopy and scanning electron microscopy.
