Abstract
AbstractWe 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 of1Lnand2Lnwere established by single crystal X‐ray diffraction, while for1Ybhigh resolution experiment was performed. Nitrate complexes1Lnare isomorphous and both adopt mononuclear structure. Chloride2Ybis monomeric, while Eu3+analogue2Euadopts a binuclear structure due to two μ2‐bridging chloride ligands. The typical lanthanide luminescence was observed for europium complexes (1Euand2Eu) 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)).
