具有不稳定阴离子的金属簇合物如[BuaNjziMoeCPgiOSOzCFa）^] 1和[BiL] 2的合成用途|N] 2 [Mo 6-CPgCCOzCFs）^]是最近发现的。2-4这些化合物与较强的配位阴离子如OAc-和中性离子如PR 3或吡啶以及不常见的配体如[（NC）Mn（CO）2Cp]-发生配体取代反应。2· 3通过这种途径可以获得各种各样的新金属簇衍生物，这将大大扩展六金属钼和钨簇的光化学诱导氧化还原化学。5在本说明中，我们报道了类似的轻配位钽簇合物[BiuNMTae-Clii 2（0 SO2 CF 3）a6]（=2-4）的制备，并证明了它们容易取代以产生12-金属超簇合物。簇合物[MeCl'sCOSChCFsFe] 2-（=
The synthetic utility of metal cluster compounds with labile anions such asiBuaNjziMoeCPgiOSOzCFa)^] 1 and [BiL| N] 2 [Mo6-CPgCCOzCFs)^] was demonstrated recently. 2-4 These com-pounds undergo ligand substitution reactions with stronger coordinating anions such as OAc-and neutrals such as PR3 or pyridine and unusual ligands such as [(NC) Mn (CO) 2Cp]-. 2· 3 The wide variety of new metal cluster derivatives that are accessible through this route should greatly expand the photochemically induced redox chemistry of the six-metal molybdenum and tungsten clusters. 5 In the present note we report the preparation of analogous lightly coordinated tantalum cluster compounds [BiuNMTae-Clii2 (0S02CF3) a6](=2-4) from [BuaNLtTaeClizCle] and demonstrate their facile substitution to produce a 12-metal supercluster.
