TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Claimed): Preparation of (I) comprises reacting an indium (III) salt of formula (InX3) initially in the presence of an alcohol of formula (ROH) and in the presence of a secondary amine compound of formula (HNR3a2) to form an indium (III)-halo-alkoxide adduct or indium (III)-oxo-halo-alkoxide adduct followed by reaction with at least one alpha -hydroxy carboxylic acid ester compound of formula (R1aCH(OH)COOR2a). Preferred Components: The indium (III)-halo-alkoxide adduct has a structure of formula (InX(OR)2(HNR3a2)y), preferably (InCl(OCH3)2(HN(CH3)2)2), (InCl(OCH2CH3)2(HN(CH3)2)2), (InCl(OCH2CH2CH3)2(HN(CH3)2)2), (InCl(OCH(CH3)2)2(HN(CH3)2)2), (InCl(OCH2CH2CH2CH3)2(HN(CH3)2)2), (InCl(OCH(CH3)(CH2CH3))2(HN(CH3)2)2), or (InCl(OC(CH3)3)2(HN(CH3)2)2). The alpha -hydroxy carboxylic acid ester compound is lactic acid methyl ester, ethyl lactate, n-propyl lactate or and n-butyl lactate. Preferred Process: The process is carried out in an alcoholic solution and the alcohol is methanol, ethanol, n-propyl alcohol, iso-propyl alcohol, n-butyl alcohol, butan-2-ol or tert-butyl alcohol. SPECIFIC COMPOUNDS - 1 Compound (I) is specifically claimed i.e. indium oxo alkoxide compound of formula (In6O2Cl6(OCH2CH3)6(CH3CH(O)COOCH2CH3)2(HN(CH3)2)2).    EXAMPLE - Indium(III) chloride (5 g) was dissolved in dried methanol (250 ml) in a moisture free glass round bottom flask under an inert gas atmosphere, with a backlog of less than 10 wt.% of indium(III) chloride remaining. Then dimethylamine (5 g) was added to the reaction mixture over a period of 5 hours. The solution was evaporated completely, the remaining solids were added to 250 ml of dried methanol, filtered under an inert atmosphere of nitrogen, washed several times with methanol and dried under vacuum (less than 10 mbar) for 12 hours at room temperature to form indium(III) chloride-methoxide-dimethylamine adduct. The indium(III) chloride-methoxide-dimethylamine adduct (5 g) was dissolved in ethanol (100 ml) in a moisture free glass round-bottomed flask under an inert gas atmosphere. The resulting slightly turbid solution was filtered and ethyl lactate (5 ml) was added. After stirring for 1 hour at room temperature, butyl acetate (5 ml) was added for crystallization. After two days crystals of indium oxo alkoxide compound of formula (In6O2Cl6(OCH2CH3)6(CH3CH(O)COOCH2CH3)2(HN(CH3)2)2) were isolated.
