The thulium bis((cyclooctane-1,5-diyl)dihydroborate) complex (THF)3Tm{(μ-H)2(BC8H14)}3 including the hydrogen bridged Tm-H-B three-center, two electron bond was prepared in the metathesis reaction of 1:3 molar ratio of TmCl3 with K[H2BC8H14] in THF at room temperature. The coordinated THF in the complex can not be removed under dynamic vacuum, remaining bound to Tm. From single-crystal X-ray analysis, the structure of the complex was shown to possess the coordination geometry around Tm atom consisting of a pseudo octahedral arrangement of three (μ-H)2(BC8H14) groups and three THF ligands. Each 9-BBN cyclic organohydroborate ligand is attached to Tm through Tm-H-B bridges. The distance of Tm to the α hydrogen is well beyond consideration for an agostic interaction. The crystal system is a monoclinic. R1 and wR2 are 0.0267 and 0.0481, respectively.
