基于二羟基萘二磺酸根的配合物Na3Na5(dhns)2·(phen)4·2H2O的合成、晶体结构和热稳定性

摘要

A new complex,Na3[Na5(dhns)2]·(phen)4·2H2O,was obtained from the self-assembly of disodium 2,7-dihydroxy-naphthalene-3,6-disulfonate (Na2H2dhns) and 1,10-phenanthroline (Phen) in a water-ethanol solution.The compound was characterized by elemental analysis,IR,TGA,and X-ray diffraction single crystal structure analyses.The compound crystallizes in the orthorhombic system,space group Pna21,a=2.829 85(12) nm,b=1.038 99(14)nm,c=2.259 23(13) nm,V=6.642 6(10) nm3,Z=4,Dc=1.573 g·cm-3,R1=0.050 6,wR2=0.124 0,S=1.05.CCDC:881794.%2,7-二羟基萘-3,6-二磺酸二钠盐(Na2H2dhns)与邻菲罗啉在乙醇/水溶液中自组装得到一新的配合物Na3[Na5(dhns)2]· (phen)4·2H2O (1),并用CHN元素分析、IR、TGA和X-射线单晶衍射分析进行了表征.晶体属正交晶系,Pna21空间群,a=2.829 85(12) nm,b=1.038 99(14) nm,c=2.259 23(13) nm,V=6.642 6(10) nm3,Z=4,Dc=1.573 g·cm-3,R1=0.050 6,wR2=0.124 0,S=1.05.
