Abstract

Graphical abstract: Two rare organically templated 2-D layered thiocyanato-chlorocadmates were synthesized, and their structures were reported. Abstract: Based on a strategy of incorporating the SCN − group into the organically templated halocadmate, the reactions of CdCl2, SCN −, and bisimidazole molecules in a strong acidic environment at 4 °C were carried out, creating two new organically templated 2-D layered thiocyanato-chlorocadmates [H2 (L1)][Cd2 Cl5 (SCN)] (L1 = bis(1H-imidazole-1-yl)methane)1 and [H2 L2]2 [Cd5 Cl12 (SCN)2 ] (L2 = 1, 3-bis(2-ethylimidazol-1-yl)propane)2 . Both layers are based on a kind of tetranuclear Cd–Cl cluster. Since the employed organic cations are different, the neighboring tetranuclear Cd–Cl clusters are linked together by the different bridges into the 1-D endless chains. In1, the Cl − ions act as the bridges, while in2, the CdCl6 units serve as the bridges. Finally, the 1-D Cd–Cl chains are further linked by SCN − into the 2-D layer networks of1 and2 . Both layers possess a simple (4, 4) topology. Based on the structural characterization of the title compounds, the role of the introduced SCN − group on the organically templated halocadmates is discussed.
