FIELD: chemistry.
SUBSTANCE: invention relates to coordination chemistry, specifically to preparation of initial reagents for syntheses without water molecules. The method of producing an anhydrous yttrium thiocyanate complex characterised by the chemical formula [Y(18-crown-6)(NCS)3], or [Y(18-crown-6)(NCS)3]-nSol, where Sol is a solvent molecule, involves reaction of a hexahydrate of yttrium thiocyanate Y(NCS)3·6H2O with a crown ether denoted 18-crown-6 in solvents selected from: acetonitrile, tetrahydrofuran, ethyl acetate, isopropanol, with molar ratio 18-crown-6:yttrium=1.0-2.0, the reaction being carried out in an air atmosphere at temperature of 15-30°C.
EFFECT: invention enables to obtain fully dehydrated yttrium thiocyanate complexes in a single step, use readily available and cheap organic solvents, cut power consumption, and also enables to obtain novel compounds suitable for replacing expensive organometallic reagents.
