The hydrothermal (solvothermal) reactions of Zn II , Co II , and Cu II salts with the thiazole‐based ligands 2‐Htzc (thiazole‐2‐carboxylic acid), 4‐Htzc (thiazole‐4‐carboxylic acid), and Htzc‐py [2‐(2‐pyridyl)thiazole‐4‐carboxylic acid] led to the formation of coordination complexes with assorted geometry at the metal centers. The new complexes were characterized by conventional spectroscopic methods as well as by single‐crystal X‐ray analysis, TG–MS, and PXRD. Crystallographic studies have shown that an extended supramolecular network is generated in the solid state through the formaton of hydrogen bonds between the several polar groups present in the complex frameworks.
