“…This fact may be due to the existence of four S…I interactions involving both the terminal iodine atoms of triiodide anion in 2b, organized in such a way that the anion is trapped into the cage of four neighboring organic cations (Figure 3b). This fact can lead to a higher retention of iodine in the melt, as typically the first decomposition stage of polyiodides usually includes the loss of I2 from the triiodide anion [64,65]. Similar conclusions concerning melting and decomposition of crystals with C-Se…O/N chalcogen bonds were found in a recent study [66].…”

The interrelation between noncovalent bonds and physicochemical properties is in the spotlight due to the practical aspects in the field of crystalline material design. Such study requires a number of similar substances in order to reveal the effect of structural features on observed properties. For this reason, we analyzed a series of three substituted thiazolo[2,3-b][1,3]thiazinium triiodides synthesized by an iodocyclization reaction. They have been characterized with the use of X-ray diffraction, Raman spectroscopy, and thermal analysis. Various types of noncovalent interactions have been considered, and an S…I chalcogen bond type has been confirmed using the electronic criterion based on the calculated electron density and electrostatic potential. The involvement of triiodide anions in the I…I halogen and S…I chalcogen bonding is reflected in the Raman spectroscopic properties of the I–I bonds: identical bond lengths demonstrate different wave numbers of symmetric triiodide vibration and different values of electron density at bond critical points. Chalcogen and halogen bonds formed by the terminal iodine atom of triiodide anion and numerous cation…cation pairwise interactions can serve as one of the reasons for increased thermal stability and retention of iodine in the melt under heating.

“…The formation of iodides as intermediates is a known phenomenon, which was observed in the case of some higher organic polyiodides. 49,73,74 The iodine content in the intermediate product may also indicate the presence of I 2 adducts but at a temperature around 285 °C their presence is strongly unlikely. The absence of the mass signals higher than m/z = 127 in the mass spectra (Fig.…”

“…As polyiodides, especially with a high iodine ratio, are rather unstable compounds and can decompose under heating, 54 it is very important to thoroughly control the surface of a sample after the spectrum registration. The thermal stability of polyiodides usually decreases as the iodine content increases.…”
