At temperature below 100°C, ethylene glycol was found to displace water from oxalates to give a new solvate compound according to the reaction MnC2O4·nH2O+HOCH2CH2OH=MnC2O4(HOCH2CH2OH) +nH2O↑. The crystals of the solvates retain the morphology of the initial oxalates, which is then inherited by the products of their thermolysis. Thus, thermolysis of MnC2O4·3H2O and MnC2O4(HOCH2CH2OH) having quasi-unidimensional structure gave Mn3O4 and Mn2O3nanowhiskers in air and MnO in an inert gas environment. Heating of MnC2O4·nH2O in ethylene glycol at temperatures above 100°C results in anhydrous manganese oxalate Доп.точки доступа: Krasil'nikov, V. N.; Красильников Владимир Николаевич; Bazuev, G.
