“…data (Table 19) are also consistent with the structure of The 100-MHz proton n.m.r. spectrum is also consistent with the proposed formulation (Table 19); again the resonances ascribed to the (2,4), (5,6), (2',4'), and 5',6') protons were not individually resolved but the 4:2 intensity pattern of the bridging protons in the diplatinum parent compound (Table 5) had given way to the 2 : 2 : 1 ratio expected for the symmetrical product. In addition the Pt-hydride resonance at 6 -6.3 p.p.m.…”

“…However, the differences between the oxide and hydroxide are small, indicating that the electronic effects of the -OB,,H, , and -OH groups on the 6-position of the nido-decaborane cluster are very similar. At 32 MHz the two compounds are best distinguished by their "B (6) resonances at + 26.1 and + 21.8 p.p.m. for the hydroxide and oxide respectively, which are resolved in mixtures of the two species in common n.m.r.…”

“…Decaborane derivatives with an exo-polyhedral B-B bond also include isomeric conjuncto-decaboranes [B 10 H 13 ] 2 , which consist of two nido-B 10 units linked by a direct B-B bond. These compounds were first identified as trace impurities in technical decaborane (l4) [349]. In principle, there can be 11 different geometric isomers of conjuncto-decaborane [B 10 H 13 ] 2 , 4 of which are in the form of enantiomeric pairs.…”

“…The first examples of such metallaboranes were reported by Earl Muetterties and Russell Grimes in the early 1970s. In 1974 Norman, Russell Grimes and Alan Davison independently synthesized the key compound [(CO) 3 FeB 4 H 8 ] (figure 4), which they published jointly (3). As noted, this compound can alternatively be regarded as a borane-ligand analogue of the well-known organometallic species [Fe(CO) 3 (η-C 4 H 4 )] or, alternatively, as a derivative of B 5 H 9 in which the apical {BH} fragment has been replaced by an isolobal {Fe(CO) 3 } fragment, although it would not be for a further two years until Roald Hoffmann and co-workers developed the isolobal concept.…”
