- W4382932541 abstract "Abstract Building upon our earlier results on the chemistry of nido ‐1,2‐[(Cp*RuH) 2 B 3 H 7 ] (Cp*= ɳ 5 ‐C 5 Me 5 ) ( nido ‐ 1 ) with different transition metal carbonyls, we continued to investigate the reactivity with group 7 metal carbonyls under photolytic condition. Photolysis of nido ‐ 1 with [Mn 2 (CO) 10 ] led to the isolation of a trimetallic [(Cp*Ru) 2 {Mn(CO) 3 }( μ ‐H)( μ ‐CO) 3 ( μ 3 ‐BH)] ( 2 ) cluster with a triply bridging borylene moiety. Cluster 2 is a rare example of a tetrahedral cluster having hydrido(hydroborylene) moiety. In an attempt to synthesize the Re analogue of 2 , a similar reaction was carried out with [Re 2 (CO) 10 ] that yielded the trimetallic [(Cp*Ru) 2 {Re(CO) 3 }( μ ‐H)( μ ‐CO) 3 ( μ 3 ‐BH)] ( 3 ) cluster having a triply bridging borylene unit. Along with 3 , a trimetallic square pyramid cluster [(Cp*Ru) 2 {Re(CO) 3 }( μ ‐H) 2 ( μ ‐CO)( μ 3 , ɳ 2 ‐B 2 H 5 )] ( 4 ), and heterotrimetallic hydride clusters [{Cp*Ru(CO) 2 }‐{Re(CO) 4 } 2 ( μ ‐H)] ( 5 ) and [{Cp*Ru(CO)}{Re(CO) 4 } 2 ( μ ‐H) 3 ] ( 6 ) were isolated. Cluster 4 is a unique example of a M 2 M′B 2 cluster having diboron capped Ru 2 Re‐triangle. The hydride clusters 5 and 6 have triangular RuRe 2 frameworks with one and three μ ‐Hs respectively. All the clusters have been characterized by using mass spectrometry, 1 H, 11 B{ 1 H}, 13 C{ 1 H} NMR and IR spectroscopies analyses and the structures of clusters 2 – 6 have been unambiguously established by XRD analyses. Furthermore, to understand the electronic, structural, and bonding features of the synthesized metal‐rich clusters, DFT calculations have been performed." @default.
