Synthesis, Crystal Structure and Photoluminescence of a New Zn(Ⅱ) Dimer Constructed by 1,10-Phenanthroline Derivative and Flexible Dicarboxylate

摘要

A new compound,[Zn(L)(1,4-chdc)]2·2H2O(1,1,4-chdc = 1,4-cyclohexanedicarboxylate and L = 11-fluoro-dipyrido[3,2-a:2,3-c]phenazine),has been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction.The crystal of 1 belongs to triclinic,space group P1 with a = 9.4679(19),b = 10.915(2),c = 12.577(3) ,α = 77.22(3),β = 74.73(3),γ = 65.47(3)°,C52H39F2N8O10Zn2,Mr = 1104.65,V = 1131.4(4) 3,Z = 1,Dc = 1.621 g/cm3,S = 1.091,μ(MoKα) = 1.143 mm–1,F(000) = 565,R = 0.0426 and wR = 0.1171.In 1,two 1,4-chdc anions bridge two Zn(Ⅱ) atoms to form a dimer.The neighboring dimers are further extended by π-π stacking interactions to form a 2D supramolecular layer.The luminescent property of the compound has also been investigated.
