두 가지의 팔면체형 Ni(Ⅱ)-polyethyleneimine (PEI) 착물, [Ni(PEI)]Cl2 및 [Ni(PEI)Cl2]를 합성하여 과산화수소 분해반응에서 이들 착물의 촉매활성도를 조사하고, 유사한 구조를 한 ethylenediamine 착물, [Ni(en)3]Cl2 및 [Ni(en)2Cl2]의 촉매활성도와 비교해 본 결과, 다음과 같은 순서로 촉매 활성도가 증가함이 관찰되었다 : 0 ≒ [Ni(en)3]Cl2 ≤ [Ni(en)2Cl2] < [Ni(PEI)]Cl2 < [Ni(PEI)Cl2] 가시선 및 적외선 흡수 스펙트럼을 측정하여 두 가지 Ni(Ⅱ)-PEI 착물의 구조를 조사하여 본 결과 이들 착물의 촉매활성도는 배위자와 Ni(Ⅱ)이온사이의 결합세기에 의존함을 알 수 있었다.

Two types of Ni(Ⅱ)-polyethyleneimine (PEI) complexes, [Ni(PEI)]Cl2 and [Ni(P-EI)Cl2] were synthesized and their catalytic activities in the decomposition reaction of hydrogen peroxide were investigated. For the purpose of comparison, the corresponding monomeric complexes, [Ni(en)3]Cl2 and [Ni(en)2Cl2] were also prepared; it was observed that their activities increase in the following order; 0 ≒ [Ni(en)3]Cl2 ≤ [Ni(en)2Cl2] < [Ni(PEI)]Cl2 < [Ni(PEI)Cl2] On the basis of structural analysis by means of visible and infrared spectroscopy, the catalytic activiy of these Ni(Ⅱ)-PEI complexes is assumed to depend on the bond strength between the ligand and the nickel ion.
