摘要:
Reaction of [IrCl2(eta (5)-C5Me5)](2) with the [hypho-CSB6H11](-) anion gives [2,7-(eta (5)-C5Me5)(2)-nido-2,7,8,6-Ir2CSB6H8] and [2,7-(eta (5)-C5Me5)(2)-nido -2,7,8,6-Ir2CSB6H7-9-Cl] which exhibit composite cluster features in which the {IrSIrC} string and the {B-6} unit occupy separate domains within the overall contiguous nido-type ten-vertex {Ir2SCB6} cluster unit.
