Two novel divalent transition metal disulfonates were synthesized and characterized by X-ray single crystaldiffraction. [Ni(cyclam)(1, 5nds) ] @ 1/3H2O (1) crystallized in space group P2(1)/c with unit cell parametersa = 8.583(5), b = 10. 533(6), c= 12. 946(7) A, and β=92. 433(9)°. The Ni2+ center is coordinated by thecyclam ligand and two sulfonate groups. The interactions between [Ni(cyclam)] 2+ and the sulfonates are furthertallized in space group Pl with unit cell parameters a = 8.738(5), b = 9. 324(5), c = 10. 118(5)A, α = 81. 382(8), β=64. 868(8), and y= 62.999(8)°. The sulfonate groups do not have any direct contact with the Co2+center, instead, they form second sphere coordination with Ni2 + via hydrogen bonds and extend the structure into a3-D network. CCDC: 194341, 194342.%合成了两个二价的过渡金属磺酸化合物,并通过X-射线衍射单晶结构分析进行结构表征.化合物[Ni(cyclam)(1,5nds)]@1/3H2O(1)以P2(1)/c空间群结晶,晶胞参数为a=8 583(5),b=10.533(6),c=12.946(7)A,β=92.433(9)°.[Ni(cyclam)]2+与两个磺酸基团形成弱配位,从而构筑了一维的配聚物.[Ni(cyclam)]2+与磺酸基团之间的作用还通过O2S-O…H-N型氢键进一步被加强.化合物[Co(cyclam)(H2O)2](1,5nds)@2H2O(2)以Pl空间群结晶,晶胞参数为a=8.738(5),b=9.324(5),c=10.118(5)A,α=81.382(8),β=64 868(8),γ=62.999(8)°.在该化合物中,磺酸基团没有与Co2+形成配位键,而是以平衡离子的形式存在并与配离子形成氢键,构筑了有序的三维结构.
