Abstract

We report the synthesis of Ln3+ nitrate [Ln(Tpm)(NO3)3] ⋅ MeCN (Ln=Yb (1Yb), Eu (1Eu)) and chloride [Yb(Tpm)Cl3] ⋅ 2MeCN (2Yb), [Eu(Tpm)Cl2(μ‐Cl)]2 (2Eu) complexes coordinated by neutral tripodal tris(3,5‐dimethylpyrazolyl)methane (Tpm). The crystal structures of 1Ln and 2Ln were established by single crystal X‐ray diffraction, while for 1Yb high resolution experiment was performed. Nitrate complexes 1Ln are isomorphous and both adopt mononuclear structure. Chloride 2Yb is monomeric, while Eu3+ analogue 2Eu adopts a binuclear structure due to two μ2‐bridging chloride ligands. The typical lanthanide luminescence was observed for europium complexes (1Eu and 2Eu) as well as for terbium and dysprosium analogues ([Ln(Tpm)(NO3)3] ⋅ MeCN, Ln=Tb (1Tb), Dy (1Dy); [Ln(Tpm)Cl3] ⋅ 2MeCN, Ln=Tb (2Tb), Dy (2Dy)).
