1,2,4-triazine derived binuclear lead(ii) complexes: synthesis, spectroscopic and structural investigations and application in organic light-emitting diodes (OLEDs).

Two novel binuclear complexes of Pb(ii) were synthesized by reacting a 3-(2-pyridyl)-5-(4-methoxyphenyl)-1,2,4-triazine (PMPT) ligand with different anionic co-ligands (1: bromide, 2: acetate and isothiocyanate) in a 1 : 1 molar ratio of PMPT ligands to lead(ii) salts. The complexes, [Pb(μ-PMPT)Br] (1) and [Pb(μ-PMPT)((μ-CHCOO)(NCS)] (2), were characterized using various physicochemical techniques such as CHN analysis, FT-IR spectroscopy, and H NMR spectroscopy. Additionally, their structures were determined using single-crystal X-ray diffraction.
