| Abstract: | By simply changing pH value of reaction solution, three low-dimensional iodoargentate hybrids, HDABCO]2(DABCO)2(Ag2I4)] (1), HDABCO]0.5(HDABCO)0.5(AgI2)] (2) and (Me2NH2)(H2DABCO)]AgI4] (3) (DABCO = 1,4-diazabicyclo-2.2.2]octane), have been synthesized. Noteworthy, variation in protonated degree and aggregating forms of DABCO at different pH value, the structure of inorganic moieties vary regularly from 0D (DABCO)2(Ag2I4)]2? anion for 1 to 1D (HDABCO)0.5(AgI2)]0.5? chain for 2 and 0D AgI4]3? anion for 3, exhibiting unique structural directing effects. In addition, three compounds display structure-dependent semiconductor natures and thermal stabilities. |
