The hydrothermal reaction of Gd(III) salt with a new rigid dicarboxylate ligand, N,N'-dioxide-3,3'-benzocinnoline dicarboxylic acid (H2L) give rise to a new metal-organic framework (MOF) {[Gd(L)(1.5)(H2O)(2)]center dot 2H(2)O}(n) (1). The MOF 1 shows 3D microporous framework with 1D parallelogram like channels which are constructed by single rod-shaped {Gd(CO2)(2)}(n) chains. The thermal stability, UV/Vis diffuse-reflection spectra, magnetic properties of 1 in the temperature range 2-300 K have been explored. Also its photocatalytic property against the photo-degradation of aromatic dye Rhodamine B (Rh B) has been studied and the plausible photocatalytic mechanism has been addressed using density of states (DOS) calculations.
