Ytterbium metal reacts with thallium(I) 3,5‐diphenylpyrazolate, or with diphenylmercury and 3,5‐diphenylpyrazole (Ph 2 pzH) in tetrahydrofuran or 1,2‐dimethoxyethane (DME) giving, after appropriate isolation, the first lanthanoid(II) pyrazolate complex, [Yb(Ph 2 pz) 2 (DME) 2 ]. The molecular structure reveals eight coordinate ytterbium(II) with two cisoid η 2 ‐3,5‐diphenylpyrazolate and two chelating 1,2‐dimethoxyethane ligands.
