Abstract
|
|
|
|
Several new nickel(II) complexes, [Ni(L)X2 and [Ni(L)2]Cl2 (L = L1, L2 ; X = Cl-, Br-, I-) have been synthesized by reacting NiX2 or NiX2, 6H2O with aminophosphines(L) wherein L is 1,2-bis{(diphenylphosphino)amino}propane(L1) or 1,2-bis{(diphenylphosphino)amino}ethane(L2). These complexes are characterized by the optical spectroscopic methods (UV/Vis, CD, IR, 1H-NMR, and 31P-NMR) together with conductometer and elemental analysis. The complex with I- is tetrahedral, where the complexes with Cl- or Br- are square planar. The complexes, [Ni(L)X2](X = Cl-, Br-) become tetrahedral, as they react with methyl iodide. The Ni(L)X$_2$ 수식 이미지 complexes underwent solvolysis with a various organic solvents such is EtOH, DMSO, THF and DMF.
