与此同时，本课题还对两种配合物进行红外、PXRD、介电、热重等相关性质的研究与测定。在介电测试过程中并没有发现大的介电异样峰，说明两种配合物没有发生相变。

Abstract One coordination compound C8H18N 2+·2ReO4-(1) was obtained based on

(CH3-Dabco-CH3)2+·2Br− ligand。Selecting good crystal structure crystals and single crystal of compound 1 are obtaining by single-crystal diffractometer。 And then we definiting the unit cell parameters of single crystal 1。Among it, compound 1 crystallizes in the Orthorhombic crystal system at room temperature (296K) , it belongs to space group Pbam,the molecular weight is 361。38 and its cell parameters for a=8。7697(5)Å,b=12。4207(5)Å,c=6。7970(3)Å,α=β=γ=90。00°,V=740。37(6)Å3,Z=4,

One coordination compound C6H14N2O 2+·2ReO4-(2) was obtained based on

Dabcodo ligand。 Selecting good crystal structure crystals and single crystal of compound 2 are obtaining by single-crystal diffractometer。 And then we definiting the unit cell parameters of single crystal 2。Among it,compound 2 crystallizes in the monoclinic crystal system at room temperature (296K) , it belongs to space group P21/n,,the molecular weight is 1577。50 and its cell parameters for a=6。6208(2)Å,b=14。2890(4)Å,c=10。2314(3)Å,α=90。00°,β=91。3240(10)°,γ=90。00°,V=

At the same time, this issue also do some research and measurement of infrared, PXRD, dielectric, TG and other related properties of the two compounds 。 And we did not find a large dielectric unusual peak in the dielectric testing process,so it proves there is no phase transition of them。
