Polymorphism and Thermally Induced Structural Transformation in Semiconducting Cd(II) Coordination Polymers.

ABSTRACT: Three polymorphs of a semiconducting Cd(II)-thiolate coordination polymer with the formula [Cd(2-SNPh)₂]_n (2-HSNPh = 2-naphthalenethiol) have been reported. Single-crystal X-ray structural analysis revealed that KGF-51 adopts a one-dimensional (1D) structure composed of single-strand (-Cd-S-)_n ladder chains, whereas KGF-71 adopts a 1D architecture with double-strand (-Cd-S-)_n chains assembled through S···S interactions. In contrast, microcrystal electron diffraction analysis demonstrated that KGF-79, obtained through thermal treatment of KGF-51 and KGF-71, exhibits the formation of a 1D structure comprising triple-strand (-Cd-S-)_n chains, also formed via S···S interactions.
