Binary Group 13 cyanides [PPh 4 ][Ga(CN) 4 ], [PPh 4 ] 2 [In(CN) 5 ], and [PPh 4 ] 2 [Tl(CN) 5 ] were obtained in quantitative yields from the corresponding metal trifluorides MF 3 (M=Ga, In, Tl) by fluoride–cyanide exchange reactions with Me 3 SiCN in the presence of stoichiometric amounts of [PPh 4 ]CN in acetonitrile solution. The 2,2′‐bipyridine (bipy) adducts [(bipy) 2 Ga(CN) 2 ][Ga(CN) 4 ], [(bipy)In(CN) 3 ], and [(bipy)Tl(CN) 3 ] were obtained from the reaction of MF 3 with Me 3 SiCN and bipy in acetonitrile. While the reaction of the metal trifluorides with Me 3 SiCN in acetonitrile resulted in recovery of the starting materials, the reaction of MF 3 with Me 3 SiCN in pyridine (py) solution resulted in the formation of the pyridine adducts [(py) 2 Ga(CN) 3 ], [(py) 3 In(CN) 3 ], and [(py) 2 Tl(CN) 3 ]. The cyano compounds were characterized by their vibrational spectra and, in most cases, by their X‐ray crystal structures.
