The syntheses and characterizations of the first bismuthanylborane monomers stabilized only by a donor in D<middle dot>BH2Bi(SiMe3)2 (D = DMAP 1a, IDipp 1b, IMe41c; DMAP = 4-dimethylaminopyridine, IDipp = 1,3-bis(2,6-diisopropylphenyl)-imidazolin-2-ylidene, IMe4 = 1,3,4,5-tetramethylimidazol-2-ylidene) are presented. All compounds were synthesized by salt metathesis reactions between D<middle dot>BH2I and KBi(SiMe3)2(THF)0.3 and represent some of the extremely rare compounds featuring a 2c-2e B-Bi bond in a molecular compound. The products display high sensitivity towards air and light and slowly decompose in solution even at -80 degrees C. By the reaction of IDipp<middle dot>GaH2(SO3CF3) with KBi(SiMe3)2(THF)0.3, the synthesis of the first bismuthanylgallane IDipp<middle dot>GaH2Bi(SiMe3)2 (2) stabilized only by a 2-electron donor was possible, as evident from single crystal X-ray structure determination, NMR spectroscopy and mass spectrometry. Computational studies shed light on the stability of the products and the electronic nature of the compounds. The syntheses of first, extremely sensitive donor-stabilized monomeric bismuthanylboranes D<middle dot>BH2Bi(SiMe3)2 (D = NHC, DMAP) and the bismuthanylgallane IDipp<middle dot>GaH2Bi(SiMe3)2 are presented representing unique element combinations of bismuth and triels.
