摘要
在水、甲醇和N,N’-二甲基甲酰胺(DMF)的混合溶液中以2,4-双(2-(苯甲酸)苯巯甲基)-1,5-二甲苯(2,4-bis(2-(benzylacid)thiophenylmethyl)-1,5-dimethylbenze)、吡啶(pyridine)、硝酸钴为原料采用水热法合成了标题配合物Co[2,4-bis(2-(benzylacid)thiophenylmethyl)-1,5-dimethylbenze]2(pyridine)2。配合物晶体属正交晶系,空间群Pbcn。晶体结构表明:钴原子与两个吡啶的两个N原子、两个2,4-双(2-(苯甲酸)苯巯甲基)-1,5-二甲苯中的四个羧基氧原子配位,晶胞参数:a=1.6958 nm,b=0.959 6(2)nm,c=3.191 6 nm,V=5.193 8(5)cm3,Dc=1.397 g.cm-3,Z=4,F(000)=2 276,GooF=0.999,R1=0.036 9,wR2=0.096 2。对晶体进行了热稳定性分析,结果表明:配合物在420℃以前稳定存在。
One cobalt(Ⅱ)coordination polymer was synthesized with 2,4-bis(2-(benzylacid)thiophenylmethyl)-1,5-dimethylbenze,pyridine and cobalt nitrate in the solvent mixture of water,methanol and DMF.Crystal data for this complex: orthorhombic,space group: Pbcn,a=1.695 8 nm,b=0.959 6(2) nm,c=3.191 6 nm,V=5.193 8(5) cm3,Dc=1.397g·cm-3,Z=4,F(000)=227 6,GooF=0.999,R1=0.036 9,wR2=0.096 2.The crystal structure shows that the Cobalt ion was coordinated with two nitrogen atoms of two pyridine molecules and four oxygen atoms from two 2,4-bis(2-(benzylacid)thiophenylmethyl)-1,5-dimethylbenze molecules.The result of TG analysis showed that the title complex was stable until 420 ℃.
