{Ge9R3Cr(CO)5}- and {Ge9R3Cr(CO)3}-: a metalloid cluster (Ge9R3-) as a flexible ligand in coordination chemistry [R=Si(SiMe3)3].
The reactions of the metalloid cluster {Ge9[Si(SiMe3)3]3}- with Cr(CO)5COE (COE=cyclooctene) and Cr(CO)3(CH3CN)3 lead to the new cluster compounds {Ge9[Si(SiMe3)3]3Cr(CO)5}- and {Ge9[Si(SiMe3)3]3Cr(CO)3}-, whose structural and electronic properties are presented.
