水热条件下合成了新颖的三维网状配位聚合物[Ce4 (tzda)6 (H2O)10]n(H2tzda为1,3,4-噻二唑-2,5-二硫代乙酸),对其结构进行了红外、元素分析和X射线单晶衍射测定.该配合物属三斜晶系,空间群P1,晶胞参数a=1.372 4(2) nm,b= 1.665 3(2) nm,c=1.815 2(3) nm,a=104.270(2)°,β=107.900(2)°,γ= 105.653(2)°,Z=2.在晶体结构单元中,存在有4个晶体学独立的Ce(Ⅲ)离子,4个Ce(Ⅲ)离子均与氧原子配位,其中3个为九配位,1个为八配位;配体阴离子tzda2-则展示了4种完全不同的配位模式,并通过这些配位模式将Ce(Ⅲ)离子连接成复杂的三维网状结构.此外,在室温条件下对配合物的荧光性质进行了测定.%A novel 3D coordination polymer, [Ce4 (tzda) 6 ( H2O) 10 ]n [ H2 tzda = ( 1,3,4-thiadiazole-2,5-diyldithio)diacetic acid], was hydrothermally synthesized and characterized by IR, elemental analysis and X-ray single crystal diffraction. The title complex crystallized in triclinic space group P(1), with a=1. 372 4(2) nm, b=1. 665 3(2) nm, c=1. 815 2(3) nm, α=104. 270 (2)°, β=107. 900(2)°, γ= 105. 653(2)° and Z= 2. In each structural unit, four Ce( Ⅲ ) ions were all coordinated with oxygen atoms, three of them were nine-coordinated while the other one was eight-coordinated; and tzda2- ligands displayed four different coordination modes. Through these coordination modes, Ce(Ⅲ) ions were connected by ligands to form a complicated 3D network. Furthermore, the luminescent property of the title complex was also investigated.
