Adjusting the structures of lanthanide(III) complexes by variation of the metal sources: From a 2D (32.4)(34.43.52.65.7) layer to an unusual 3D (412.63)(49.66) nia network
چکیده انگلیسی

A novel coordination polymer [La(L)(H2O)]n (1) has been prepared by hydrothermal reaction of 5-hydroxyisophthalic acid (H3L) with La(NO3)3·6H2O, which exhibits an unusual three-dimensional (3D) (6,6)-connected nia net with Point (Schläfli) symbol of (412.63)(49.66). Meanwhile, a two-dimensional (2D) (3,6)-connected (32.4)(34.43.52.65.7) coordination network {[Ho2(HL)3(H2O)2]·H2O}n (S1) was also obtained with partially deprotonated HL2– ligand. Comparison of the structural differences between 1 and S1 suggests that the different metal sources play an important role in the construction of such coordination networks.

Two coordination polymers, [La(L)(H2O)]n (1) and {[Ho2(HL)3(H2O)2]·H2O}n (S1) (H3L = 5-hydroxyisophthalic acid), have been prepared. Complex 1 exhibits the nia topological net with Point (Schläfli) symbol of (412.63)(49.66), whereas complex S1 has a 2D (3,6)-connected (32.4)(34.43.52.65.7) topology. Remarkably, complex 1 is the first lanthanide network with the hydroxyl group of 5-hydroxyisophthalic acid coordinating to the metal atoms.Figure optionsDownload as PowerPoint slideHighlights
