A new three-dimensional coordination polymer [Ce_2(C_4H_4O_4)_3(H_2O)_2]_n·3.2 nH_2 O, constructed by Ce(Ⅲ) ion and succinate ion and lattice water molecules has been synthesized under hydrothermal conditions. It crystallizes in triclinic system, space group P1 with a = 7.8865(6), b = 12.0260(8), c = 12.2598(9) ?, α = 112.456(2)o, β = 90.046(2)o, γ = 100.423(2)o, Mr = 722.14, V = 1053.73(13) ?~3, Z = 2, Dc = 2.276 g/cm~3, μ = 4.35/mm, F(000) = 696, GOF = 1.029, R = 0.0203 and w R = 0.0570. The asymmetric unit contains two Ce~(3+) cations and both of them are nine-coordinated and their coordination geometries can be described as two distorted monocapped square antiprisms. In the title compound, a three-dimensional coordination network with one-dimensional hexagon honeycomb-like channels along the a axis is generated. TG measurement has been carried out, and its result analysis along with the powder XRD determination indicates the residue to be CeO_2. 相似文献

The complex [Cu( μ3-I)INH]n has been synthesized in DMF solution with INH, CuI, where INH=isoniazid. The crystal structure of the complex has been determined by X-ray diffraction single crystal structure analysis. The crystal belong to monoclinic system, space group P21/c. The cell parameters are: a=1.009 48(10) nm, b=0.467 51(5) nm, c=1.992 62(19) nm, β=101.413 0(10)°, and V= 0.921 81(16) nm3, Z=4, μ(Mo Kα)=5.674 mm-1, F(000)=616.0, R1=0.031 6, wR2=0.082 5 [I2σ(I)]. The copper(Ⅰ) atom locates in a distorted coordination tetrahedron. The copper(Ⅰ) atoms bridged by μ3-I to form a band stair-like chain, and INH occupying the remaining coordination site of the approximately tetrahedral. The stair-like chains extend along b axis. The results of TG analysis show the title complex was stable under 200℃. 相似文献

合成和表征了两个类似的三齿席夫碱配体(L1)-和(L2)-的铜[Ⅱ]配合物[CuL1I](1)和[CuL2I](2)(HL1为2-(2-pyridyl)-N-[1-(1H-pyrrol-2-yl)ethylidene]ethanamine;HL2为N-[1-(1H-pyrrol-2-yl)ethylidene](2-pyridyl)methanamine),并用红外光谱、电喷雾质谱、紫外-可见光谱、单晶X-射线衍射和热重分析等手段对配合物进行了表征。对配合物1的X-射线晶体结构测定表明它是一个畸变的平面正方形单核铜[Ⅱ]配合物。晶体结构还表明,除了配体的柔性和空间限制外,分子间的相互作用也是影响铜[Ⅱ]配合物结构的因素。 相似文献
