A new Cd(II)-MOF (1) was successfully synthesized on the basis of a new long double Schiff-base ligand and Cd(SCN)(2). Its crystal structure was determined by X-ray diffraction. In 1, each pair of Cd(II) nodes is bridged by two inversely related mu-SCN- to form infinite inorganic chains with the remaining two trans-positions being occupied by two Schiffbase figands to generate a 3D framework with rhombus-like channel (similar to 9 x 9 angstrom). 1 can reversibly absorb CH2Cl2 and CHCl3 at different temperature without collapsing of the host framework. Furthermore, it displays a strict size selectivity and can completely separate these volatile chlorocarbons of CH2Cl2 and CHCl3 in liquid and vapor phases.
