We present new insights into the ligand strength of the metalloid [Ge9(Hyp)3]− cluster (Hyp=Si(SiMe3)3) alongside novel neutral Ge9 clusters of the composition R3PAuGe9(Hyp)3 (R=Et, nPr, iPr, nBu, tBu, Cy). These clusters are synthesized in good yields from KGe9(Hyp)3 and R3PAuCl. Further experiments with these new clusters show that the ligand strength of [Ge9(Hyp)3]− is in between aryl and alkyl phosphines
我们本新的见解准金属的配位体强度[葛9脯氨酸(Hyp)3 ] -簇脯氨酸(Hyp = SI(森达3)3)并排新颖中性葛9组合物R的簇3 PAuGe 9脯氨酸(Hyp)3(R =Et, n Pr, i Pr, n Bu, t Bu, Cy)。这些簇是由 KGe 9 (Hyp) 3和 R 3 PAuCl以良好的产率合成的。这些新簇的进一步实验表明 [Ge 9 (Hyp) 3 ]的配体强度-介于芳基膦和烷基膦之间。
