Synthesis, crystal structure and other properties of the complexes of Er(III), Yb(III) and Lu(III) with 4,4′-bipyridine and dichloroacetates

“…They are also isostuctural in the group: Y, Ce, Pr, Nd, Eu [16]. On the other hand, the complex of Tm(III) [20] is of the type as complexes of Er, Yb and Lu. All complexes in series with 4-bpy and dichloroacetates are hydrated.…”

“…3 The selected IR spectra of gaseous products from thermal decomposition of Yb (4-bpy) 1.5 (Cl 2 HCCOO) 3 Á3H 2 O complex isostructural in solid state compounds with general formulae Ln(4-bpy) 1.5 (Cl 2 HCCOO) 3 Á3H 2 O, whereas the complexes Y, La ? Ho (except Pm) containing one molecule of 4-bpy [16][17][18][19][20]. They are also isostuctural in the group: Y, Ce, Pr, Nd, Eu [16].…”

“…Ho (except Pm) containing one molecule of 4-bpy [16][17][18][19][20]. They are also isostuctural in the group: Y, Ce, Pr, Nd, Eu [16]. On the other hand, the complex of Tm(III) [20] is of the type as complexes of Er, Yb and Lu.…”

“…Ho, except Pm) were obtained [16][17][18][19][20]. On the other hand, the complex of Tm(III) has been isolated as Tm(4-bpy) 1.5 (Cl 2 HCCOO) 3 Á3H 2 O [20]. The compounds of Ce(III) and Nd(III) also were prepared with empirical formulae Ln(4-bpy) 1.5 (Cl 3 CCOO) 3 Á2H 2 O.…”

“…They were characterized by elemental and thermal analysis, IR and conductivity studies. A coupled TG-MS system was used to detection the principal volatile products of thermal decomposition and fragmentation processes for Nd(III), Pr(III) [16], Sm(III) [18], Dy(III) [19] and Tm(III) [20] compounds. Additionally, the crystal and molecular structure of La(III) [17] and Sm(III) [18] complexes were determined.…”
