The reaction of <5-C5Me5)Cl2>2> with nido-6-SB9H11 and a non-nucleophilic base yields <8-(η⁵-C5Me5)-nido-8,7-IrSB9H11> 1, whereas with the (1-) anion it yields <8-(η⁵-C5Me5)-9-Cl-nido-8,7-IrSB9H10> 2, <8-(η⁵-C5Me5)-10-Cl-nido-8,7-IrSB9H10> 3 and <1-(η⁵-C5Me5)-closo-1,2-IrSB9H9> 4.With , Cs yields a compound formulated as -arachno-6-SB9H11> which, on thermolysis, yields 9-(PPh3)-arachno-6-SB9H11.The crystal and molecular structures of Cs and compound 2 have been established by single-crystal X-ray diffraction analysis, and all the iridathiaboranes have been examined in detail by (1)H ad (11)B single and multiple magnetic resonance spectroscopy.
