摘要：
The crystal structure of new complexes of praseodymium(III) and ytterbium(III) (elements from the initial and final parts of the lanthanide series), namely, [Pr(NO3)3 (Terpy)((CH3)2CO)] (I) and [Yb(NO3)2(Terpy)(H2O)2]NO3 · 2H2O (II), is investigated. The structure of compound I consists of [Pr(NO3)3(Terpy)((CH3)2CO)] neutral complexes. The coordination number of the praseodymium atom is 10. The coordination polyhedron of the praseodymium atom can be described as a distorted bicapped tetragonal antiprism. The structure of compound II is composed of [Yb(NO3)2(Terpy)(H2O)2]+ cationic complexes, nitrate anions, and molecules of crystallization water. The structural components are joined together via a three-dimensional system of hydrogen bonds. The coordination polyhedron of the ytterbium atom can be represented as a distorted tricapped trigonal prism. The coordination number of the ytterbium atom is 9.
