Synthesis,Crystal Structure and Properties Research of Zn/Cd Coordination Polymers Based on 4,4′-Biphenyldicarboxylic acid

Two coordination polymers {[Zn(bpdc)(H2O)2]·H2O}n(1) and [Cd(bpdc)(H2O)2]n(2)(H2bpdc=4,4′-biphenyldicarboxylic acid) had been synthesized by gel diffusion method.The crystal structure has been determined by X-ray single crystal diffractometry.The results revealed that compound 1 crystallized in monoclinic system with space group C2/c,a=0.693 66(11) nm,b=3.160 7(5) nm,c=0.626 80(9) nm,β=96.467°,and compound 2 crystallized in orthorhombic system with space group Pnma,a=0.586 69(7) nm,b=2.914 1(4) nm,c=0.786 63(10) nm.The complexes were stable up to 400 ℃,and had strong emission at room temperature.CCDC: 800390,1;800393,2.
