Binuclear complexes of nitrates of rare earth elements M=(La, Pr, Nd, Sm, Tb, Dy, Er, Yb) with bicyclic urea - 2,4-dimethyl-2,4,6,8-tetraazabicyclo were synthesized[3.3.0]octane-3,7-dione, of assumed composition [M(C6HioN4P2)(H2P)2(NO3)3]2. The rare earth element atom is coordinated by two oxygen atoms of two 2,4-dimethylmethylglycoluryl molecules, three bidentate nitrate anions, and water molecules. For some complexes (La, Pr, Nd), mass spectrometry with inductively coupled plasma was performed, the metal: the 2,4- dimethylglycoluryl ratio was 1,9: 2.
