Resumen:
Two new holmium-succinate frameworks have been synthesized by the hydrolysis in situ of the succinylsalicylic acid under different hydrothermal conditions. Compound 1,  [Ho2(C4H4O4)3(H2O)2]·0.33(C7H6O3), Pî space group,  has a novel structure composed by 1D-SBUs consisting in [HoO9] chains of polyhedra linked by the succinate ligands giving a 3D framework. Compound 2, [Ho2(C4H4O4)3(H2O)2], also belonging to the Pî space group, has a denser structure. The role of the in situ-generated salicylic acid on the formation of both structures is studied by means of a synthesis design methodology. A topological study of the new holmium succinate compounds in comparison with the previous reported 3D holmium-succinate framework is performed here.
