摘要

利用水热法合成了新的配位聚合物[[Co(ANA)(4,4′-bpy)1.5 (H2O)2]n·n(ANA)；ANA为8-氨基萘酸根,bpy为联吡啶],利用元素分析、红外光谱及X射线单晶衍射分析了其组成和结构.单晶结构解析结果表明,标题化合物属于单斜晶系,P21/c空间群；其晶胞参数为:a=1.149 80(10) nm,b=2.644 4(3) nm,c =1.155 21(10) nm,β=112.270(2)°,V=3.250 5(5) nm3,Mr=701.61,Dc=1.434 g/cm3,μ(Mo Kα)=0.584 mm-1,F(000)=l 456,Z=4,R1=0.062 4,wR2=0.145 9.%A new supramolecular coordination polymer,[Co(ANA) (4,4′-bpy)1.5 (H2O)2]n ·n(ANA) (ANA =8-amino-1-naphthoate,bpy =bipyridine),was prepared via a hydrothermal route.The composition and structure of as-synthesized complex were analyzed by elemental analysis and infrared spectrometry as well as single-crystal X-ray diffraction.Results indicate that the complex crystallizes in monoclinic system of space group P21/c,with unit cell parametersbeinga =1.149 80(10) nm,b =2.644 4(3) nm,c =1.155 21(10) nm,β =112.270(2)°,V =3.250 5(5) nm3,Mr =701.61,Dc =1.434 g/cm3,μ(Mo Kα) =0.584mm-1,F(000) =1 456,Z =4,R1=0.062 4 and wR2=0.145 9.
