Synthesis,Crystal Structure and Thermal Property of a 2D Brick Wall Framework Constructed from a New Mononuclear Complex

摘要

One new coordination polymer with the chemical formula [CoCu2L2·K2·1.5C2H5OH]n(H4L = 2-hydroxy-3-[(E)-({3-[(2-hydroxybenzoyl)amino]propyl}imino)methyl] benzoic acid) has been synthesized based on the slow diffusion method,and characterized by IR spectroscopy,thermalgravimetric and X-ray diffraction analysis.It crystallizes in the monoclinic system,space group P21/n with a = 11.98860(10),b = 24.4279(3),c = 14.9008(2) ,β = 104.7490(10)°,V = 4220.01(8) 3,Z = 2,Mr = 1009.94,Dc = 1.590 g/cm3,F(000) = 2056,μ(MoKα) = 1.649 mm-1,the final R = 0.0411 and wR = 0.1178 for 5920 observed reflections with I > 2σ(I).The compound possesses a 2D brick wall structure constructed from trinuclear units.
