Four corresponding Zn(II)、Ni(II)、Mn(III)、Cu(II) transition metal complexes were herein synthesized using N,N′-bis(2-hydroxy-1-naphthaldehyde) ethylenediamine reduction schiff base as ligand,and their structures we...
A Schiff base ligand was synthesized by condensating 5-bromosalicylaldehyd with ethylenediamine and several rare earth complexes,such as La(Ⅲ)、Ce(Ⅲ)、Nd(Ⅲ) were synthesized.The compositions and structures of the l...
The complex VO(SALEN)was synthesized by the reaction of vanadyl sulfate and H2salen.The complex was dissolved in CH2Cl2 and green needle crystal was obtained.It was characterized by elemental analysis,IR and X-ray d...
N,N’-bis(salicylidene)ethylenediamin complexes with rare earth ions,Nd(Ⅲ),Gd(Ⅲ) and Yb(Ⅲ),were synthesized and characterized with elemental analysis,UV-Vis spectroscopy,infrared spectroscopy and TG-DTG analysis.Th...
The mechanism of the reaction of N β dydroxyethylethylenediamine (HEDA) on copper under catalysis for the synthesis of piperazine was studied.The structures of reaction mixtures were identified by GC MS.The prelimina...
