Abstract
MCl2(M=Mo; z=5, M=V; z=3)과 N,P 주개 리간드를 acetonitrile 용매에서 반응시켜 중성 착물 [MCl3(phda)(MeCN)]과 [MCl3(PPh3)2(MeCN)] (M=Mo, V)을 합성하였다. Acetone 용액에서 이들 중성착물과 AgClO4를 반응시켜 양이온 착물 [MCl3-nL2(MeCN)(S)n](ClO4)n (n=1, 2 : s=solvent)을 얻었다. 염소가 연결된 [(MeCN)(phda)ClM(μ-Cl)2M'Cl(PPh3)2(MeCN)](ClO4)2 및 pyrazine이 연결된 [(MeCN)(phda)Cl2M(μ-pyz)M'Cl2(PPh3)2(MeCN)](ClO4)2형의 호모(M=M'), 헤테로 (M≠M') 이핵 착물을 합성하였다. 합성한 착물들은 원소분석과 적외선, 1H, 13C 핵자기 공명 및 전자 흡수스펙트럼을 이용하여 그 특성을 조사하였다.

The neutral complexes [MCl3(phda)(MeCN)] and [MCl3(PPh3)2(MeCN)] (M=Mo, V) were prepared by the reaction of MClz, (M=Mo; z=5, M=V; z=3) with N, P-donating ligands in acetonitrile solution. Addition of AgClO4 to these neutral monomeric complexes in acetone solution afforded [MCl3-nL2(MeCN)(S)n](ClO4)n (n=1, 2 : s=solvent). Two types of asymmetrical homo- and hetero-dinuclear complexes have been synthesized. The type of chloride bridged dinuclear complex is [(MeCN)(phda)ClM(μ-Cl)2M'Cl(PPh3)2(MeCN)](ClO4)2. And the type of pyrazine bridged complex is [(MeCN)(phda)Cl2M(μ-pyz)M'Cl2(PPh3)2(MeCN)](ClO4)2. These complexes were characterized by elemental analysis, 1H, 13C NMR, IR, Far-IR and UV-Vis spectroscopy.
