| Abstract: | A series of chain multinuclear cobaltacarboranes of the general formula (C2B9H11)2Co n (C2B8H10) n?1] n?, wheren = 4 to 7, were synthesized. These compounds, containing derivatives ofortho-carborane(12) as ligands and dicarbollide C2B9H1 2? and bidentate dicarbacanastide C2B8H11 4? ligands, were studied by IR, UV, and H and11B NMR spectroscopy. The nonequivalence of the dicarbacanastide ligands that occupy different positions in the chain with respect to the terminal dicarbollide ligands was discovered. |
