Studies concerning synthesis, structure and luminescence of eight-coordinate Eu, Tb, Sm Dy complexes the type [Ln(acac)2(L)]Cl (Hacac = pentanedione-2,4 L bis(5-(pyridine-2-yl)-1,2,4-triazol-3-yl)propane) are reported in detail. The obtained were investigated by various means including elemental- thermogravimetric analysis, IR- electron transition spectroscopy. Tb complex was determined single-crystal X-ray crystallography: is eight-coordinate, acting only as a tetradentate chelate together...
A multidentate hydrazone-type ligand (Z,Z)-bis(1-(pyridin-2-yl)-1-amino-methylidene)oxalohydrazide (H2L) was utilized in the synthesis of three new isomorphous tetranuclear complexes general formula [Ln4(HL)4(H2L)2(NO3)4](NO3)4·4CH3OH (Ln = GdIII, 1, TbIII, 2, DyIII, 3) with gridlike [2 × 2] topology. The analysis static magnetic data revealed weak anti-ferromagnetic interaction among lanthanide(III) atoms, whereas dynamic led to observation single-molecule magnet behavior zero field for Dy4...
A nine new Zn(II) complex were synthesized based on a Salen-type tetradentate N2O2 ligands derived from 1-phenyl-3-methyl-4-formyl-5-pyrazolone. Complexes have been characterized by single-crystal X-ray diffraction, ESI-mass spectroscopy, elemental analysis, IR spectroscopy and thermal gravimetric analysis. UV–vis, emission electrochemical studies indicated that changes of the electronic states diamine moieties are main parameter influences absorption color investigated zinc(II) complexes.

New zinc and magnesium complexes of N-(2-carboxyphenyl)salicylidenimine) were synthesized structurally characterized by elemental analysis, FT-IR, X-ray single-crystal analysis. These exhibit tuneable luminescence in the solid state from blue to green varying metal ion composition. Moreover, quantum yields range 0.11 0.41, while lifetimes determined be nanosecond timescale. Thermal analysis shows that these good thermal stability can therefore well used as electroluminescent materials.
