利用水热法在均苯三甲酸、六水氯化钴、甲酸铵和水的体系中合成了四水合均苯三甲酸二氢钴。该化合物晶体属于单斜晶系,对应的空间群为P2/c。磁性测量表明该化合物的钴离子之间存在反铁磁的相互作用,但直至2K时也没有观察到磁有序。
Co(H2BTC)2(H2O)4 was synthesized under hydrothermal condition in the system of H3BTC, CoCl2·6H2O, NH4CHOO, and water. It crystallizes in monoclinic space group P2t/c with a=0.511 15(13) nm, b=1.299 5(3) nm, c= 1.516 1 (4) nm, and β=96.859(6)° Magnetic measurements showed that an antiferromagnetic interaction occurred between the Co(Ⅱ) ions in Co(H2BTC)2(H20)4, but no antiferromagnetic ordering was found down to 2 K.
