초록
2-Pyridine aldoxime (Pyoxime)을 리간드로 이용하여 망간(II) 착화합물 [Mn2Cl4(Pyoxime)2(H2O)2]을 합성한 후 magnetic moment, electron spin resonance spectroscopy (ESR), electron spectroscopy for chemical analysis (ESCA) 및 X-ray diffraction spectroscopy (XRD)를 이용하여 성질과 구조를 조사한 결과, 착화합물은 중심금속 Mn(II)과 Pyoxime 리간드의 2개의 N과 메탄올의 O, 3개의 Cl(-) 이온이 일그러진 팔면체 형태로서 이핵 착화합물을 이루며 배위 결합하고 있었다. 중심금속 Mn(II)과 Pyoxime 리간드는 거의 평면의 형태를 띠고 있었다. 결정이 형성되는 과정에서 하나의 단위세포는 다른 두 개의 이핵 착화합물로 구성되어 있으며 3차원 망상 구조를 이루고 있었다. 한편 무기 표백제로 널리 사용되는 과탄산나트륨의 저온 표백활성화제로서 이용을 검토하기 위해 적포도주, 모린 및 커피 오염액과 오염포에 대한 표백활성화력을 평가한 결과 우수한 효과를 나타내어 공업적으로 이용 가치가 상당할 것으로 기대된다.
A manganese complex, [Mn2Cl4(Pyoxime)2(H2O)2], was synthesized with 2-Pyridine aldoxime (Pyoxime) as a ligand. This research has investigated the properties and structure using magnetic moment, ESR, ESCA, and XRD. This complex is six coordinated having a distorted octahedron structure ; two nitrogen atoms of the Pyoxime ligand, one oxygen atom of methanol and three chlorine ions are coordinated to Mn(II) that is nearly on the same plane of the Pyoxime ligand. In each unit cell there are two different binuclear complex forming the three dimensional networking structure. An evaluation of the bleaching effect of the Mn complex as a bleaching activator of sodium percarbonate was performed using red wine, morin, and coffee soiled solutions and fabrics at low temperatures. As the result shown very good bleaching power by using the Mn complex, we expect it will offer a good industrial application.
