Abstract: The complete structure of {K(MeTHF)3}2{Yb{(μ-H)2BC8H14}4} including the positions of the H atoms has been determined by single-crystal neutron diffraction on the quasi-Laue diffractometer VIVALDI at the Institut Laue-Langevin in Grenoble, France. Each [(μ-H)2BC8H14]− ligand is coordinated to the Yb atom via two Yb–H–B bridges, and two out of the four [(μ-H)2BC8H14]− units exhibit C–H···Yb agostic interactions. Crystallographic details: space group C2/c (Monoclinic); a =17.62 (4), b =19.92(4), c =21.05 (4)Å; β =95.62(9)Å; Z =4. Final agreement factor: R(F)=13.5% for 1668 unique reflections with I >2σ(I).
