用硫酸钴、4,4’-联吡啶和2-磺酸基乙基膦酸合成了一个新颖的钴化合物:[Co2(H2O)8(C10H8N2)2].(HO3PCH2CH2SO3)(SO4)(H2O)4,并对其进行了红外。元素分析、热重测试,通过单晶衍射仪测定了其晶体结构。结果表明,配合物属单斜晶系C2/c空间群,分子式为C22H45Co2N4O22PS2,分子量为930.57,晶胞参数为a=19.8456(18),b=11.2957(10),c=34.719(3),β=106.095(3)°,晶胞体积为7477.9(12)3,Z=8,Dc=1.653 g/cm3,F(000)=3856,μ=1.131 mm-1,最终残差因子R1=0.0726,wR2=0.1719(相对于5612个I>2σ(I)的可观测衍射点)。在这个化合物中,二齿配体4,4’-联吡啶把Co(II)桥连成[Co(4,4’-bipy)]2+链。化合物中的[Co(4,4’-bipy)]2+链有三个不同的朝向。2-磺酸基乙基膦酸没有参与配位而是做为一个有机模板剂填充在[Co(4,4’-bipy)]2+链形成的空隙中。
A novel cobalt compound was synthesized from cobalt sulfate, 4,4’-dipyridyl and 2-sulfonic acid ethylphosphonic acid: [Co2 (H2O) 8 (C10H8N2) 2] (HO3PCH2CH2SO3) (SO4) 4, and its infrared. Elemental analysis, thermogravimetry and their crystal structures were determined by single crystal diffractometer. The results show that the complex belongs to the monoclinic C2 / c space group with the molecular formula of C22H45Co2N4O22PS2 and the molecular weight of 930.57. The unit cell parameters are a = 19.8456 (18), b = 11.2957 (10), c = 34.719 = 106.095 (3) °, the unit cell volume is 7477.9 (12) 3, Z = 8, Dc = 1.653 g / cm3, F (000) = 3856, μ = 1.131 mm-1 and the final residual factor R1 = wR2 = 0.1719 (observable diffraction point relative to 5612 I> 2σ (I)). In this compound, the bidentate ligand 4,4’-bipyridine bridges Co (II) into [Co (4,4’-bipy)] 2+ chains. The [Co (4,4’-bipy)] 2+ chains in the compounds have three different orientations. 2-sulfoethylphosphonic acid did not participate in the coordination but was filled as an organic template in the gap formed by [Co (4,4’-bipy)] 2+ chains.
