Under hydrothermal conditions,isonicotinic acid reacted with BiCl 3 to give 1D zigzag chain complex [(C 6 H 6 NO 2) 2 ·(BiCl 5)·2H 2 O] n (1).Single-crystal X-ray determination shows that compound 1 crystal-lizes in the monoclinic system,space group C2/c with a=13.115(3),b=19.957(4),c=7.9374(16),β=97.45(3)°,Z=4,V=2060.0(8) 3,C 12 H 16 BiCl 5 N 2 O 6,D c=2.162 g/cm 3,M r=670.50,λ(MoKa)=0.71073,μ=9.237 mm-1,F(000)=1272,R=0.0208 and wR=0.0503.Dielectric constant of compound 1 was measured at different conditions.Measurements on the dielectric properties of 1 showed that the 1D chain coordination polymer exhibited a dipolar chain relaxation process and a relatively high dielectric constant. 相似文献
