摘要:In this work,a new two-dimensional Cd(Ⅱ) coordination polymer,[Cd3(L)2(cis-1,4-chdc)2(trans-1,4-chdc)](1,L = 11-fluoro-dipyrido[3,2-a:2’,3‘-c]phenazine and 1,4-H2 chdc = 1,4-cyclohexanedicarboxylatic acid),has been prepared under hydrothermal conditions.It crystallizes in triclinic,space group P1 with a = 8.6951(8),b = 10.8362(9),c = 14.9445(13) ?,α = 76.443(2),β = 81.8670(10),γ = 82.0640(10)°,V = 1347.0(2) ?3,Z = 1,C60H48Cd3F2N8O12,Mr = 1448.26,Dc = 1.785 g/cm3,F(000) = 722,μ(Mo Ka) = 1.255 mm-1,R = 0.0333 and w R = 0.0790.The 1,4-chdc2-carboxylates bridge the Cd(Ⅱ) cations to form a tri-nuclear Cd(Ⅱ) cluster,which are held together by the cis-1,4-chdc2-ligands to generate a double-stranded chain.Further,the trans-1,4-chdc2-ligands bridge adjacent double-stranded chains to yield an interesting two-dimensional network.The π-π interactions among L ligands of neighboring networks result in an interesting three-dimensional supramolecular architecture.In addition,the thermal behavior and luminescent property of 1 have been studied.
