The new complex of [H2en][Cu(pydc)2].2H2O (1) (where H2en and pydc are ethylenediammonium and 2,6-pyridinedicarboxylate, respectively) was synthesized by the reaction of a mixture of ethylenediamine (en) and 2,6-pyridinedicarboxylic acid (H2pydc) in a mixture of CH3OH/H2O as solvent. This complex was fully characterized by elemental analysis, IR, UV–Vis spectroscopy as well as single-crystal X-...

here, we report the synthesis of a schiff-base mixed-ligand complex of cadmium(іі) in bulk and nano-scales via the precipitation and sonochemical methods, respectively. the complex formula is [cd(3-bpdh)(3-bpdb)cl2]n (1), where the ligands are 3-bpdh = 2,5-bis(3-pyridyl)-3,4-diaza-2,4-hexadiene and 3-bpdb = 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene. the structure of mixed-ligand complex (1) wa...
