| Abstract: | Two isostructural CdII frameworks, Cd2(MMA)2(bpy)(H2O)2]n ( 1 ) and Cd2(MMA)2(bpe)(H2O)2]n ( 2 ), were synthesized solvothermally with hybrid flexible methylmalonic acid (H2MMA) and rigid 4,4'-bipyridine (bpy) or trans-1,2-bis(4-pyridyl)ethylene (bpe) as coligands. Single-crystal X-ray diffraction analyses reveal that complexes 1 and 2 display a three-dimensional (3D) framework structure composed of 2D Cd(MMA)] layer unit and bpy/bpe linker, and exhibit a (3,4)-connected topological network with Schläfli symbol of {63}{65.8}. The solid-state luminescent properties were studied, and 1 and 2 show a distinct emission centered at 465 and 531 nm, respectively. |
