簇合物ＮＥｔ＿４ＲｕＣｏ＿３（ＣＯ）＿（１２）［１］分别与配体三苯基膦（ＰＰｈ＿３）和二苯基膦（ＰＰｈ＿２Ｈ）反应，得到双取代产物ＮＥｔ＿４Ｃｏ＿３（ＣＯ）＿（１０）（ＰＰｈ＿３）＿２［５］．双取代产物进一步质子化，则得到具有相应结构的中性簇合物ＨＲｕＣｏ＿３（ＣＯ）＿（１０）（ＰＰｈ＿３）＿２［４Ａ］和ＨＲｕＣｏ（ＣＯ）＿（１０）（ＰＰｈ＿２Ｈ）＿２．它们的结构通过元素分析，红外，￣１ＨＮＭＲ。￣（３１）ＰＮＭＲ和有关反应确认。两个取代基均为一个膦占据了与钴结合的位置（Ｃｏ－Ｐ），而另一个膦占据了与钌结合的位置（Ｒｕ－Ｐ）。
The complex of NEt_4RuCo_3 (CO) _ (12) [1] was reacted with triphenylphosphine (PPh_3) and diphenylphosphine (PPh_2H) respectively to obtain the double substituted product NEt_4Co_3 (CO) _ (10) _2 [5]. The double-substituted products were further protonated to give the corresponding clusters of HRuCo_3 (CO) _ (10) (PPh_3) _2 [4A] and HRuCo (CO) _ (10) (PPh_2H) _2. Their structure through elemental analysis, infrared, ~ 1HNMR. ~ (31) PNMR and related reactions confirmed. Both phosphines occupy a cobalt-bound site (Co-P) for both substituents, while the other phosphine occupies the Ru-P binding site.
