GLYCOLIC ALCOHOLATES FORMATION IN M(M)CUO(N)-ETHYLENE GLYCOL SYSTEMS

X-ray, microscopic, and thermogravimetric analyses were used to study the interaction of Bi2-xSr2Ca2Cu3O10+y, Ca2CuO3, Sr2CuO3, CaSrCuO3, Sr CuO2, BaCuO2, and Li2CuO2 powders with ethylene glycol at room tempera ture. It was determined that glycolic alcoholates are obtained as a re sult of interaction of simple cuprates and ethylene glycol. The compou nds M(2)[Cu(CH2OCH2OH)(6)] (M = Ca, Sr), M[Cu(CH2OCH2O)(2)] (M = Sr, B a), Li-2[Cu(CH2OCH2OH)(4)], and Li-2[Cu(CH2OCH2O)(2)(H2O)(2)] have bee n isolated and identified. Chemical transformation of Bi2-xSr2Ca2Cu3O1 0+y leads to the formation of glycolic alcoholates mixture with the co mpositions Sr[Cu(CH2OCH2O)(2)], Ca-2[Cu(CH2OCH2OH)(6)], CaSr[Cu(CH2OCH 2OH)(6)], and the unidentified amorphous phases containing bismuth and lead.
