Abstract: | Transparent orange crystals of [Yb(MeCp)2(O2CC6F5)]2 and [Yb(MeCp)2(O2C‐o‐HC6F4)]2 were obtained by oxidation of Yb(MeCp)2 with M(O2CR) (M = 1/2 Hg, Tl; R = C6F5, o‐HC6F4) 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 Pbca. Room temperature as well as low temperature single crystal X‐ray investigations show the o‐H/F positions in [Yb(MeCp)2(O2C‐o‐HC6F4)]2 not to be ordered. |
