Abstract
Novel lanthanide based two-dimensional metal–organic framework (MOF) compound [Dy(NDC)(NO3)(DMA)2]n (1) [H2NDC = 2,6-naphthalenedicarboxylic acid and DMA = N,N-dimethylacetamide] has been synthesized through solvothermal route and structurally characterized. Structural analysis reveals that compound is crystallized in the orthorhombic crystal system with space group Pbca. MOF features “paddle-wheel” (PW) core building units which are constructed via carboxylato oxygen coordinated to lanthanide atoms. Remaining coordination sites of the octa-coordinated metal center are occupied by oxygen atoms of DMA and NO3− ions. Paddle-wheel cores of 1 are interconnected to each other to give rise to layered network structure. The morphology of the MOFs as well as different types of weak interactions possessed by the framework have been assessed using Hirshfeld surface analysis and fingerprint plots have been drawn to understand various interactions. Notably, compound 1 can efficiently catalyze the N-arylation reaction heterogeneously.
