In compound 1, L2- ligands link Cd（II） to form a sinusoidal ruffling layer, in which the carboxylic groups connect Cd（II） into an infinite Cd--O chain. And the layers are further stabilized by hydrogen bonding and π-π in- teractions, forming a three-dimensional（3D） supramolecular network. In addition, the fluorescent property of compound 1 was also investigated.展开更多
