Abstract
The invention relates to new multinuclear coordinated compounds, simultaneously containing: copper atoms, barium atoms and atoms at a rare terrestrial element Lanthanum in the proportion Cu:Ba:Ln=4:2:1 and N1, N4-double emicarbazide - as a chelation ligand.The summary of the invention consists in the fusion of a new group of multinuclear N1, N4-double isosemicarbazides, containing copper atoms, barium and lanthanum atoms in the ratio of 4:2:1 with the following formulaThey are obtained by the interaction of barium di [N1, N4-double- isosemicarbazidoî cuprite and lanthanum hydroxide (Ln=Y, La, Sm, Dy, Yb), in the proportion of 2:1 in the mixture of chloroform and ethanol (10:1), warming up to (40-50°C) and continuous stirring for 1,5-2 hours.The technical effect of the invention consists in the creation of a new group of multinuclear coordinated compounds containing copper, barium and Landthanum atoms in the p ratio of 4:2:1 and double semicarbazide - as a chelation liguand. These substances may be used as initial products for obtaining polycrystalline ceramics of perowskit structure with a high conductivity at high temperature.
