The phys. properties of the organic-inorganic hybrid crystals having the formula [NH3(CH2)3NH3]ZnX4 (X = Cl, Br) were investigated. The phase transition temperatures (TC; 268K for Cl and 272K for Br) of the two crystals bearing different halogen atoms in their skeletons were determined through differential scanning calorimetry. The thermodn. properties of the two crystals were investigated through thermogravimetric anal. The structural dynamics, particularly the role of the [NH3(CH2)3NH3] cation, were probed through 1H and 13C magic-angle spinning NMR spectroscopy as a function of temperature The 1H and 13C NMR chem. shifts did not show any changes near TC. In addition, the 1H spin-lattice relaxation time (T1¦Ñ) varied with temperature, whereas the 13C T1¦Ñ values remained nearly constant at different temperatures The T1¦Ñ values of the atoms in [NH3(CH2)3NH3]ZnCl4 were higher than those in [NH3(CH2)3NH3]ZnBr4. The observed differences in the structural dynamics obtained from the chem. shifts and T1¦Ñ values of the two compounds can be attributed to the differences in the bond lengths and halogen atoms. These findings can provide important insights or potential applications of these crystals.
