Synthesis and structure study of a novel 2D network polymeric cadmium(II) complex bridged by thiocyanate

A distorted honeycomb-like cadmium–thiocyanate framework with the formular [BMIM]2[Cd2(SCN)6] has been synthesized by self-assembling through electrostatic interaction between cadmium–thiocyanate network and N,N′-dialkylimidazolium ions. The [BMIM]+ cations acting as the spacers and controllers dominate the dimension of the complex.
