Solid-State Structures of Trialkylbismuthines BiR₃ (R = Me, <i>i</i>‑Pr)

Two trialkylbismuthines BiR3 (R = Me (1), i-Pr (2)) were structurally characterized by single-crystal X-ray diffraction. Single crystals were grown using an IR-laser-assisted technique. 1 forms short intermolecular Bi···Bi interactions in the solid state, which were further investigated through quantum chemical computations with ab initio coupled cluster and dispersion-corrected density functional methods.
