Abstract
Self-assembly FeII complexes of phenazine (Phen), quinoxaline (Qxn), and 4,4'-trimethylenedipyridine (Tmp) with tetrahedral building blocks of [HgII(XCN)4]2- (X = S or Se) formed six new high-dimensional frameworks with the general formula of [Fe(L) m ][Hg(XCN)4]·solvents (L = Phen, m/X = 2/S, 1; L = Qxn, m/X = 2/S, 2; L = Qxn, m/X = 1/S, 3; L = Qxn, m/X = 1/Se, 3-Se; L = Tmp, m/X = 1/S, 4; and L = Tmp, m/X = 1/Se, 4-Se). 1, 3, and 3-Se show an intense sub-terahertz (sub-THz) absorbance of around 0.60 THz due to vibrations of the solvent molecules coordinated to the FeII ions and crystallization organic molecules. In addition, crystals of 1, 4, and 4-Se display low-frequency Raman scattering with exceptionally low values of 0.44, 0.51, and 0.53 THz, respectively. These results indicate that heavy metal FeII-HgII systems are promising platforms to construct sub-THz absorbers.
