| Abstract: | The reaction of 2‐aldehyde‐8‐hydroxyquinoline, histamine, and YbX3 · 6H2O (X = NO3–, ClO4–) affords two ytterbium complexes Yb(nma)2] · ClO4 · 2CH2Cl2 ( 1 ) and Yb(nma)(NO3)2(DMSO)] · CH3OH ( 2 ) (Hnma = N‐(2‐(8‐hydroxylquinolinyl)methane(2‐(4‐imidazolyl)ethanamine))). The crystal structures were determined by X‐ray diffraction and it has been revealed that the anions have played important role in the assembly. In the case of 1 , the Yb3+ ions are completely encapsulated by two nma ligands with uncoordinated perchlorate anion balancing the positive charge. In the case of 2 , the Yb3+ ions are ligated by the ligand, oxygen atoms of the nitrate ion, and DMSO. Both complexes exhibit essential NIR luminescence of Yb3+ ions. |
