| 摘要: 本文报道了碱溶液中获得组份为Na4K[Cu(HIO6)2]·12H2O晶体配合物.用X-射线衍射法测定了晶体结构.晶体属单斜晶系,P21/c空间群,a=6.108(2)Å,b=25.055(10)Å,c=14.716(7)Å,β=97.77(3)°,V=2231(2)Å3,Dc=2.555g/cm3,Z=4.晶体中二个畸变的IO5(OH)八面体与中心铜原子螯合,构成CuO4平面;Cu—O平均键长为1.83Å;加上CuO4平面上侧与铜原子形成弱配位的氧原子;共有五个氧原子与铜原子构成近似为C2v点群对称的四方单锥多面体.在碱性水溶液中,配合物的紫外吸收峰的衰减表明,[Cu(HIO6)2]5-还原为一级反应. |

| Abstract: The crystal of title complex Na4K[Cu(HIO6)2]·12H2O has been obtained from alkaline solution and crystal structure was determined by four cycle X-ray diffractometer. The complex crystallizes in monoclinic system, space group P21/c with lattice parameter a = 6.108(2)Å, b = 25.055(10)Å, c=14.716(7)Å, β=97.77(3) ° , V=2231(2)Å3, Z=4, Dc=2.555g/cm3. Copper atom is chclatcd by two groups of distorted octahedral IO5(OH) to configurate CuO4 square planar with average Cu-O distance of 1.83Å, and its next nearest neighbour being one oxygen of water molecular at2.688Å over the planar. The five oxygen atoms and the copper atom forms tetragonal monopyramid configuration expected to have a approximate C2v symmetry.The stability of the complex in alkaline aqueous solution has been studied by UV absorption spectrum which shows the reduction of [Cu(HIO6)2]5- takes one-order reaction. |
