Molecular structures of {(HCDippN)2B}Sn(IPrMe)Br (1, upper), {(HCDippN)2B}SnSn(IPrMe){B(NDippCH)2} (2, centre) and K2[Sn2{B(NDipp CH)2}2] (3, lower) in the solid state as determined by X‐ray crystallography. Hydrogen atoms and solvate molecules omitted, and selected groups shown in wireframe format for clarity; thermal ellipsoids set at the 40 % probability level. Key bond lengths (Å) and angles (°): (for 1) Sn−B 2.295(5), Sn−C 2.307(5), 2.6325(8), B−Sn‐Br 98.1(1), B−Sn‐C 97.4(2), C−Sn‐Br 94.6(1); (for 2) Sn−Sn 2.581(1); Sn−B 2.243(7), 2.189(5); Sn−C 2.183(5); Sn‐Sn−B 109.1(2), 120.4(1); (for 3) Sn−Sn 2.749(1); Sn−B 2.288(3); Sn K 3.599(1), 3.575(1); Sn‐Sn−B 96.5(1).
