Abstract
Two fluorescent cadmium complexes, [HL][CdCl2(H2O)2] (1) and [HL][CdBr2(H2O)2] (2) (HL = N-succinopyridine), have been prepared and characterized by single-crystal X-ray diffraction. Complex 1 contains a unique μ2-Cl bridged neutral 2D inorganic layer, which is further connected to isolated HL molecules by hydrogen bonds forming a hamburger-like OIO 2D supramolecular architecture. Complex 2 features a 3D supramolecular network assembly from 1D inorganic chains and discrete organic molecules through hydrogen bonds. Thermogravimetric, luminescent properties and theoretical calculations of 1 and 2 are also discussed. Moreover, UV-to-Vis tunable emissions for N-succinopyridine and 1 as well as blue-to-green tunable emission for 2 are observed.
