Abstract: 
A series of [H3O]+[LnL4]-⋅nH2O complexes (n = 1-3, Ln = Nd, (1), Sm (2), Eu (3), Tb (4); HL = 3- methyl-1-phenyl-4-formylpyrazole-5-one) were synthesized and characterized. The structures of the SmIII and EuIII complexes were investigated by X-ray diffraction. The isostructutal crystalls 2 and 3 consist the tetrakis [LnL4]- anions which are linked by H-bonding with the hydroxonium counter- ion and water molecules. The lanthanide ion is situated in the center of distorted tetragonal antiprism formed by eight oxygen atoms of 4-formyl-5-hydroxypyrazolonate anions. The TbIII and SmIII complexes show strong luminescence in solid state, whereas the EuIII and NdIII complexes show low luminescence activity.
