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P21/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2 K时也没有观察到磁有序.
利用水熱法在均苯三甲痠、六水氯化鈷、甲痠銨和水的體繫中閤成瞭四水閤均苯三甲痠二氫鈷.該化閤物晶體屬于單斜晶繫.對應的空間群為P21/c.磁性測量錶明該化閤物的鈷離子之間存在反鐵磁的相互作用,但直至2 K時也沒有觀察到磁有序.

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 P21/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(H2O)4,but no antiferromagnetie ordering was found down to 2 K.CCDC: 681478.
