trinuclear substituted complexes of the type Ru 3 (CO) 9 (arphos)(L) were synthesized by a substitution reaction involving Ru 3 (CO) 10 (arphos) ( 1 ) with L, where L = PCy 3 , PPh 3 , P(C 6 H 4 F- m ) 3 , P(C 6 H 4 F- p ) 3 , P(C 6 H 4 Cl- p ) 3 and PPh(C 6 H 4 OMe- p ) 2 , using a thermal method. The structures of the resulting clusters were elucidated by single crystal X-ray diffraction, complemented
摘要通过Ru 3(CO)10(arphos)(1)与L的取代反应合成了六种Ru 3(CO)9(arphos)(L)型三核取代配合物,其中L = PCy 3,PPh 3 ,P(C 6 H 4 F-m)3,P(C 6 H 4 F-p)3,P(C 6 H 4 Cl-p)3和PPh(C 6 H 4 OMe-p)2散热方法。通过单晶X射线衍射阐明了所得簇的结构,并借助元素分析和光谱方法(包括红外光谱和1 H,13 C 1 H}和31 P 1 H} NMR光谱)进行了补充。Ru 3(CO)9(arphos)(L)中最长的Ru-Ru键[L = PCy 3(2),P(C 6 H 4 F- m)3(4),P(C 6 H 4 F -p)3(5),P(C 6 H 4 Cl- p)3(6)和PPh(C 6 H 4 OMe- p)2(7)]是单齿膦配体的顺式键,而在Ru 3(CO)9(arphos)PPh 3(3)中,
