Popis:	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 [Ln2Cl6(pyz)(thz)6]·2thz (Ln = Tb, Er), 1∞[Pr2Cl6(pyz)(thz)6], and [Ln2Cl6(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.
