【摘要】 分别将2个双吡啶酰胺配体（L¹和L²）与碘化汞进行配位反应，设计并合成了2个配位聚合物{[Hg₂（L¹）（μ₂-I）₂I₂]·2DMF·H₂O}_n（1）和{[Hg（L²）I₂]·H₂O}_n （2）。X射线单晶分析表明，这2种配合物均呈现为一维“之”字形链状结构，但通过调整配体中的3-和4-吡啶氮原子位点表现出不同的配位模式。2个配合物中Hg（Ⅱ）中心均为四配位的扭曲四面体构型。在配合物1中，Hg（Ⅱ）中心与1个3-吡啶氮原子和3个碘离子配位，配体L¹与碘化汞的物质的量之比为1∶2。在配合物2中，Hg（Ⅱ）中心与2个4-吡啶氮原子和2个碘离子配位，配体L²与碘化汞的物质的量之比为1∶1。此外，考察了2个配合物的热稳定性、固态荧光及蒸气吸附性质。更多还原

【Abstract】 Two coordination polymers,{[Hg₂（L¹）（μ₂-I）₂I₂]·2DMF·H₂O}_n（1） and{[Hg（L²）I₂]·H₂O}_n（2）,have been designed and synthesized from two dipyridylamide ligands （L¹and L²） with mercury（Ⅱ）iodide,respectively.X-ray crystallographic analyses show that both the two complexes exist as 1D zig-zag chain structures but exhibit different configurations by slightly adjusted 3-and 4-pyridyl nitrogen atoms from the ligands.Each Hg（Ⅱ）center of the two complexes is four-coordinated with distorted tetrahedral geometry.In complex1,the Hg（Ⅱ）center is coordinated by one 3-pyridyl nitrogen atom and three iodide anions in a 1∶2 molar ratio of L¹and mercury iodide.In complex2,the Hg（Ⅱ）center is coordinated by two 4-pyridyl nitrogen atoms and two iodide anions in a 1∶1 molar ratio of L² and mercury iodide.In addition,the thermal stabilities,luminescence properties,together with vapor adsorption properties of the two complexes were investigated.CCDC:2085335,L¹;2085336,L²;2085337,1;2085338,2.更多还原
