| 摘 要： | 在水热条件下采用硝酸铜和2,4,6-三甲基吡啶为原料合成了两个新的配合物Cu4（2,4,6-opyta）2（H2O）8]（1）和Cu4（2,4,6-opyta）2（H2O）6].2H2O（2）,并对配合物的结构进行了X-射线单晶衍射分析.结果表明,两配合物互为超分子异构体,结构中都包含有Cu2（2,4,6-opyta）2]基本单元,且均结晶于三斜晶系,P-1空间群,其晶胞参数分别为a=7.008 8（9）,b=8.055 0（10）,c=10.979 0（10）,α=73.419（2）°,β=87.934（2）°,γ=85.127（2）°,V=591.86（12）3和a=6.980 2（7）,b=7.067 6（7）,c=13.234 6（14）,α=82.698（2）°,β=76.977（2）°,γ=79.960（2）°,V=623.74（11）3.

| Abstract: | Two new complexes Cu4（2,4,6-opyta）2（H2O）8]（1） and Cu4（2,4,6-opyta）2（H2O）6]·2H2O（2） had been prepared hydrothermally with 2,4,6-opytaH3 and 3-hydroxy-2,4,6-pyridinetricarboxylate.The crystal structures of both complexes had been determined by X-ray analysis,3-hydroxy-2,4,6-pyridinetricarboxylate in which was in situ generated from 2,4,6-trimethylpyridine mediated by Cu2＋ under hydrothermal conditions.The results showed that two complexes were supramolecular isomers,including a Cu2（2,4,6-opyta）2] unit and crystallize in triclinic,P-1 space group.The unit cell parameters for two complexes were a=7.008 8（9）,b=8.055 0（10）,c=10.979 0（10）,α=73.419（2）°,β=87.934（2）°,γ=85.127（2）°,V=591.86（12）3;and a=6.980 2（7）,b=7.067 6（7）,c=13.234 6（14）,α=82.698（2）°,β=76.977（2）°,γ=79.960（2）°,V= 623.74（11）3,respectively. |
