Transparent orange crystals of [Yb(MeCp) 2 (O 2 CC 6 F 5 )] 2 and [Yb(MeCp) 2 (O 2 C‐ o ‐HC 6 F 4 )] 2 were obtained by oxidation of Yb(MeCp) 2 with M(O 2 CR) (M = 1 / 2 Hg, Tl; R = C 6 F 5 , o ‐HC 6 F 4 ) in tetrahydrofuran. They have a dimeric structure with bridging bidentate (O, O')‐benzoate groups and eight coordinated ytterbium. Both crystallise isotypic in the orthorhombic space group P bca. Room temperature as well as low temperature single crystal X‐ray investigations show the o ‐H/F positions in [Yb(MeCp) 2 (O 2 C‐ o ‐HC 6 F 4 )] 2 not to be ordered.
