PURPOSE: Provided is an organic alkali earth metal complex with thermal stability and good vaporization for formation of metal oxide composite films. The resultant complex is adapted to the production of semiconductors, photoelectrics and piezoelectrics. CONSTITUTION: The complex of organic alkali earth metals, L-M-L', is prepared by adding alcohol to organic solution containing alkali earth metal, expressed by the formula MX + xs HOR --£M(OR)2|n, followed by mixing with chelate ligands L and L', expressed by the formula £M(OR)2|n + L + L' --L-M-L', where M is Ba, Sr or Ca, L is R(CH3)CH(OH) (CH2)nCH(OH)(CH3)R'(R and R' are C1-C10 alkyl group, and n is an integer of 1-5), L' is N(CH2CH2XCH2CH2YZ)3(X and Y are O or NH, and Z is C1-C10 alkyl group).
