相同的水热反应条件下4-氨基-二(2-吡啶基)-1,2,4-三氮唑(abpt)、KSCN与钴盐(CoCl2.6H2O)反应合成了2种新的钴配合物:零维的单核配合物[CoSCN(abpt)](1α)和二维的无机层状配合物K2[Co3(OH)2(SO4)3(H2O)2](1β),并通过元素分析和红外光谱对其进行了表征。配合物1α的晶体属于单斜晶系,P21/c空间群。配合物1β晶体属于正交晶系,Cmc21空间群。在配合物1α中,abpt和SCN-配体都参与配位与Co!离子形成了2个不同的单核单元,这些单核单元又通过S原子和N原子之间的氢键作用连成了三维超分子结构;在配合物1β中,abpt配体没有参与配位,而SCN-配体则被氧化成了SO42-离子并与Co!离子配位形成了二维配位层状结构,相邻层之间进一步通过氢键作用形成了沿c轴方向有孔道的三维超分子网络,这些孔道里面填充着反离子K+。
Under the same hydrothermal reaction conditions, two new cobalt complexes were synthesized by the reaction of 4-amino-bis (2-pyridyl) -1,2,4-triazole and KSCN with cobalt salt (CoCl2.6H2O) The zero-dimensional mononuclear complex [CoSCN (abpt)] (1α) and the two-dimensional inorganic stratiform complex K2 [Co3 (OH) 2 (SO4) 3 (H2O) 2] Analysis and infrared spectroscopy. The crystal of complex 1α belongs to monoclinic system, P21 / c space group. Complex 1β crystal belongs to orthorhombic system, Cmc21 space group. In complex 1α, both abpt and SCN-ligands participate in coordination with Co ions to form two different mononuclear units, which in turn are connected by hydrogen bonding between S atoms and N atoms Three-dimensional supramolecular structure; in the complex 1β, abpt ligand did not participate in the coordination, and SCN-ligand was oxidized to SO42- and coordinated with the Co! Ion to form a two-dimensional coordination layer structure, phase The adjacent layers further form a three-dimensional supramolecular network with channels along the c-axis by hydrogen bonding, which are filled with counterions K +.
