A Two-dimensional Supramolecular Complex Constructed by 1,10-Phenanthroline Derivative Ligand: Synthesis, Structure and Luminescence

摘要

An unusual two-dimensional supramolecular complex,namely,[Cd2(Cl)4(L)2] (1),has been synthesized by 2-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol (L) and CdCl2·2.SH2O under hydrothermal conditions.The compound was characterized by elemental analysis,TG and single-crystal X-ray diffraction.It crystallizes in triclinic,space group P(1) with a =10.151(2),b =14.119(3),c =14.744(3) (A),a =115.744(4),β =108.063(4),γ =93.371(4)°,V=1762.7(7) (A)3,Z =2,C3sH24Cd2C14N8O2,Mr =991.25,Dc =1.868 g/cm3,F(000) =976,μ(MoKa) =1.560 mm1,R =0.0639 and wR =0.1307.In 1,two Cd(Ⅱ) atoms are bridged by two chroline atoms to give a dimer.Neighboring dimers are linked by N-H…Cl hydrogen bonds to afford supramolecular chains,which are further joined together by π-π interactions to result in a supramolecular layer.In addition,luminescent property and thermal behavior of compound 1 have been studied.
