摘要：

Four mononuclear sulfur-ligated lanthanide complexes [Ln(dtc)3dmbipy] (1-Ln, Ln = Eu, Tb, Er and Tm) were synthesized by combing the ligands of diethyldithiocarbamic acid diethylammonium salt (dtc- = diethyldithiocarbamate anion) and 4,4′-dimethyl-2,2′-bipyridine (dmbipy) with the lanthanide salts. Their single crystal X-ray diffraction data and luminescent properties were also studied. The four complexes are all crystallized in the orthorhombic Pbca space group with the [LnS6N2]-type structures. Hirshfeld surface (HS) analysis was carried out to the study the intermolecular interactions. And a comparison of the HS analysis between the title complexes and the previously published sulfur-ligated lanthanide complexes by our research group was also analyzed. In addition, the luminescence studies showed that all the four complexes can exhibit the characteristic emission peaks of the corresponding rare earth ions. © 2025
