Two Ln-based metal-organic frameworks based on the 5-(1H-1,2,4-triazol-1-yl)-1,3-benzenedicarboxylic acid ligand: syntheses, structures, and photocatalytic properties.

ABSTRACT: Two new metal-organic frameworks (MOFs) having the formula [Ln₂(H₂O)₃(L)₃·3H₂O] _n (Ln = Sm for MOF-Sm and Tb for MOF-Tb) have been synthesized solvothermally by reacting LnCl₃·6H₂O with 5-(1H-1,2,4-triazol-1-yl)-1,3-benzenedicarboxylic acid (H₂L) and characterized. Single crystal X-ray analyses for MOF-Sm and MOF-Tb revealed that both MOFs are isostructural and display a (6,8)-connected 3D structure with a point symbol of (3⁵·4⁴·6⁶)(3⁵·4⁶·5¹⁷). The natures of weak interactions existing in both MOFs have been assessed using Hirshfeld surface analyses and fingerprint plots. The utility of MOF-Sm as a photocatalyst f
