摘要(Abstract)：

新制备的CoCO_3·xH_2O加入溶有2, 6-二氟-4-溴苯甲酸、邻菲咯啉的CH_3OH/H_2O (5∶1, V/V)混合溶剂中进行水热法反应,得到一新的钴配位聚合物{Co(H_2O)(phen)(C_7H_2O_2F_2Br)_2}_n晶体.化合物结构经单晶X-衍射表征,结果表明配合物结晶于单斜晶系,P2_(1 )/c空间群,晶胞参数为:a=17.702(3)?,b=6.670(3)?,c=22.559(4)?,β=111.15(3)°,V=2 484.2(8)?³,C_(26)H_(14)O_5N_2F_4Br_2Co,Mr=729.14,Z=4,Dc=1.950 g·cm3,C_(26)H_(14)O_5N_2F_4Br_2Co,Mr=729.14,Z=4,Dc=1.950 g·cm^(-3),F(000)=1 428.最后残余因子R_1=0.053 8,wR_2=0.1 334.晶体结构中,中心Co(Ⅱ)原子六配位模式形成畸变的八面体结构,分子间经过钴与其中一个2,6-二氟-4-溴苯甲酸羧基的2个O原子配位桥联作用沿b方向形成一维链聚合物,一维双链间存在π-π芳环堆积作用构筑形成bc层.
