Abstract
Coordination compounds [Zn(H2O)4(Ur)2](NO3)2, [M(H2O)2(Ur)2(NO3)3] (M = Ce, Nd), and [Dy(H2O)(Ur)2(NO3)3] have been synthesized by the reaction of nitrates of zinc or rare earth elements with urea (Ur) in an aqueous solution. Their composition has been determined and structural features have been established using elemental analysis, IR spectroscopy, and X-ray diffraction analysis. For the zinc complex, a polymorphic transition has been found at 181 K.
