EuIII and TbIII complexes with a benzoate and a tripod N7 ligand, [LnIII(H3L)benzoate](ClO4)2·H2O·2MeOH (LnIII = EuIII and TbIII; H3L = tris[2-(((imidazol-4-yl)methylidene)amino)ethyl]amine), were synthesized and crystallized into an isomorphous structure. Each LnIII ion is coordinated by one tripod ligand and one benzoate, resulting in a nona-coordinated capped square antiprism geometry. The solid-state emission spectra displayed sharp bands of the f–f transitions. TbIII complex exhibits a magnetic anisotropy and the ac susceptibility measurements exhibited an out-of-phase signal under 1000 G bias field, indicative slow relaxation of magnetization.
