reactions of [Ru(PPh 3 ) 3 Cl 2 ], N -(benzoyl)- N ′-(5- R -salicylidene)hydrazines (H 2 bhsR, R = H, OCH 3 , Cl, Br and NO 2 ) and triethylamine (1:1:2 mole ratio) in methanol afford mononuclear ruthenium(III) complexes having the general formula trans -[Ru(bhsR)(PPh 3 ) 2 Cl]. In the case of R = H, a dinuclear ruthenium(III) complex of formula [Ru 2 (μ-OCH 3 ) 2 (bhsH) 2 (PPh 3 ) 2 ] has been isolated
摘要[Ru(PPh 3)3 Cl 2],N-(苯甲酰基)-N'-(5- R-水杨基)肼(H 2 bhsR,R = H,OCH 3,Cl,Br和NO 2的反应)和三乙胺(摩尔比为1:1:2)在甲醇中,得到具有通式反式-[Ru(bhsR)(PPh 3)2 Cl]的单核钌(III)配合物。在R = H的情况下,已分离出作为次要产物的式[Ru 2(μ-OCH3)2(bhsH)2(PPh 3)2]的双核钌(III)配合物。该复合物通过元素分析,磁性,光谱和电化学测量来表征。已经确定了双核配合物和两个单核配合物的晶体结构。在双核络合物中,每个金属中心位于由两个桥接甲醇盐基团构成的扭曲的八面体NO 4 P配位球中,一个PPh 3分子和子午跨度的酚盐-O,亚胺-N和酰胺-O供体bhsH 2−。末端PPh 3配体彼此反式。在单核络合物中,bhsR 2−和氯原子围绕金属中心形成一个NO 2 Cl方平面,两个PPh
