Abstract
π-전자받게로서 phsphrous 원자를 가지고 있는 aminophosphines류, trans-1,2-bis[diphenylphosphino)amino]cyclohexane and 1,2-bis[(diphenylphosphino) amino] propane을 포함하는 새로운 팔라듐(Ⅱ) 착물, [Pd(L)X2] (X=Cl-, Br-, I-, NCS- )을 합성하고, aminophosphine류와 한자리 리간드를 갖는 Pd(Ⅱ) 착물의 결합특성을 IR, UV 등으로 조사하였다. 7원 킬레이트 고리를 형성하는 aminophosphines 류 중에 있는 phosphorus 원자의 전자효과 및 입체효과에 따라 두자리성 리간드인 thiocyanate는 Pd-NCS로 배위되며, 한자리 리간드에 따른 분광화학 계열은 NCS- > Cl- > Br- > I-순으로 나타났다.

Several new [Pd(L)X2] complexes have been prepared with aminophosphines (L) such as trans-1,2-bis[diphenylphosphino)amino]cyclohexane and 1,2-bis[(diphenylphosphino) amino] propane that contain phosphorus atom as π-electron acceptor, and the bond character of complexes have been investigated by means of infrared and electronic spectroscopy. It was found that thiocyanate ions are N-coordinated possibly due to the steric and electronic influence of the phosphorus atom in aminophosphines that formed seven-membered chelate rings, and that spectrochemical series that is derived from the electronic spectra of the complexes is NCS- > Cl- > Br- > I-.
