三维超分子化合物Ag4(L)4(PMBS)4·2H2O的合成、晶体结构和荧光性质

摘要

The title compound,[Ag4(L)4](PMBS)4·2H2O (1),where L=2,5-bis (4-pyridyl)-3,4-diaza-2A-hexadiene,PMBS =p-methylbenzenesulfonate was synthesized and its crystal structure was determined by X-ray diffraction structure analysis.The crystal is of triclinic,space group P1 with a=0.820 3(2) nm,b=1.3227(3) nm,c=2.0610(3) nm,α=76.155(2)°,β=78.651 (4)°,γ=89.993(3)°,V=2.126 2(8) nm3,Z=2,Dc= 1.644 g·cm-3,F(000)= 1068,R=0.052 4,wR=0.113 6.The Ag atoms are linear coordinated by two N atoms of two L ligands,while the p-methylben-zenesulfonate molecules are included in the lattice and connected to [Ag(L)]n by hydrogen bonding interactions to form a three-dimensional supramoleculur structure.CCDC:727587.
