•Novel single crystal of DIAC synthesized and grown from saturated solution.•DIAC crystallize monoclinic crystal system with P21/n space group.•Metal–ligand coordination, structural properties and hydrogen bonding are discussed.•Crystalline perfection of as grown DIAC single crystal has been studied by HRXRD.
The metal–organic hybrid complex, [Cd(2ap)2I2] (DIAC), (2ap = 2-aminopyridine) was synthesized, DIAC single crystal has been grown and characterized by FT-IR, FT-Raman, FT-1H NMR, single crystal X-ray diffraction, high resolution X-ray diffraction (HRXRD), UV–Vis–NIR transmission, magnetic and thermal studies. The metal–ligand formation of the title complex was analyzed by FT-IR, FT-Raman and 1H NMR spectroscopic studies. The DIAC crystallizes in monoclinic crystal system, space group P21/n. The coordination geometry around the Cd(II) center is a distorted tetrahedral. The single-crystal structure analysis showed that DIAC displayed three-dimensional structures containing inorganic–organic motifs with two-dimensional layers pillar-connected through hydrogen bonding framework. The high resolution X-ray diffraction studies (HRXRD) reveals that the crystalline perfection of as grown single crystal is fairly good. Thermal stability of title compound was studied by TG/DTA analysis.
