Co_2(CO)_6(C_2H_2)과 Fe_2(CO)_6(C_2H_2)착물에 대한 분자궤도론적 연구 = Studies on Molecular Orbital of Co_2(CO)_6 C_2H_2)and Fe_2(CO)_6(C_2H_2)Complexes

다국어 초록 (Multilingual Abstract)

The molecular orbital of Co_2(CO)_6(C_2H_2) and Fe_2(CO)_6(C_2H_2) complexes have been studied theoritically using Extended Hu¨ckel method.(EHT-spd)
The two alternative geometries of perpendicular and parallel-bonded dinuclear transition-metal acetylene complexes have different electronic requirements.
The perpendicular acetylene as a neutral four-electron donor, two π electron donated to each metal. For the parallel acetylene as a dianion that still only contributes two electrons to each metal center.
AM(CO)_3 is isolobal with CH, the perpendicular complexes should be organic molecule tetrahedrane and the parallel acetylene complexes should be analogous to cyclobutadiene.
