A sulfur-containing Cd(II) coordination polymer assembled from 4-(4-pyridinyl)thiazole-2-thiol: synthesis, crystal structure, properties, and Hirshfeld surface analysis

Abstract

The 4-(4-pyridinyl)thiazole-2-thiol (HPTT) molecule with biological activities is a sulfur-containing organic ligand. Here, one new sulfur-containing coordination polymer based on HPTT and potassium thiocyanate (KSCN), namely, {[Cd(PTT)(HPTT)(SCN)}n, has been synthesized and characterized by physicochemical methods. The single-crystal X-ray diffraction analyses reveal the compound crystallizes in a monoclinic P21/n space group and features a one-dimensional line structure. The crystal structure is stabilized through intramolecular C–H···N and C–H···S hydrogen bonds and intermolecular N–H···N, C–H···π, and π⋯π interactions, generating a two-dimensional supramolecular layer structure. The interactions are also analyzed using Hirshfeld surface analysis. Moreover, the compound shows a relatively thermal stability and solid-state photoluminescence at room temperature.
