Complexes and coordination polymers were obtained from trivalent lanthanide chlorides together with thiazole (thz) and the diazine ligands pyrazine (pyz) and pyrimidine (pym). The compounds [ Ln 2 Cl 6 (pyz)(thz) 6 ] · 2thz ( Ln = Tb, Er), 1 ∞ [Pr 2 Cl 6 (pyz)(thz) 6 ], and [ Ln 2 Cl 6 (pym) 2 (thz) 4 ] ( Ln = Tb, Er) could be obtained, their crystal structures, luminescence as well as thermal properties were determined. The compounds with Tb and Er show intense luminescence with a strong sensitizer effect of the ligands that can be observed by dominant ligand excitation and exclusive metal emission for VIS and NIR.
