title: Solvent Directed Synthesis of Molecular Cage and Metal Organic Framework of Copper(II) Paddlewheel Cluster
abstract: Abstract A solvothermal reaction of a clip‐type dicarboxylic acid H 2 DCA [3,3′‐((5‐nitroisophthaloyl)bis(azanediyl))‐dibenzoic acid] and Cu(NO 3 ) 2 in equimolar ratio in dimethylformamide (DMF) yielded MOF(CuCG1) which was formed by interlinking [4+2] self‐assembled polyhedral cages via coordination between amide moiety present in the linker and the axial position of copper paddlewheel Cu 2 (CO 2 ) 4 . Upon a change in the solvent from DMF to DMA [dimethylacetamide] the interlinking among the
