A much improved synthesis for the carbagerma‐ closo ‐dodecaborate anion [GeCB 10 H 11 ] – is described in the form of [Bu 3 NH][GeCB 10 H 11 ] ( 1 ). In reactions with transition metal electrophiles, three transition metal complexes {[Bu 3 NH][(C 6 H 6 )Ru(Cl) 2 (GeCB 10 H 11 )] ( 2 ), [Bu 3 NH][Cp*Ir(Cl)(GeCB 10 H 11 ) 2 ] ( 3 ) and [Me 3 NH][(PPh 3 ) 2 Ir(CO)(GeCB 10 H 11 ) 2 ] ( 4 )} with metal–germanium bonds were synthesized. The carbagermaborate anion, in the form of the salt [Et 3 NH][GeCB 10 H 11 ], and the coordination compounds 2 – 4 were structurally characterized by single‐crystal X‐ray diffraction. Computations were carried out for the anions in 1 – 4 to aid NMR assignments.
