| 中文摘要: |
| 以醋酸钯(PdAc2)与亚硝酸钾(KNO2)为起始原料，水为溶剂，合成四亚硝基钯酸钾(K2[Pd(NO2)4])，产率为96.5%。采用溶剂挥发法培养出其单晶，经X射线单晶衍射分析证实:此晶体由中心对称的[Pd(NO2)4]2-配阴离子，K+阳离子和2分子结晶水组成，为三斜晶系，P-1空间群，晶胞参数为:a=6.4953(5) nm，b=7.0134(5) nm，c=7.1473(5) nm，α=118.784(2)°，β=101.050(2)°，γ=98.085(2)°，Z=1，Pd-N键长为2.014 nm和2.037 nm，∠N-Pd-N为91.70(4)°，且Pd2+位于4个N原子组成的平面四边形的中心。采用恒电位仪在室温下测试其循环伏安图，测得其还原峰电位(Ep)为-0.51 V (vs. SCE)。 |
| 英文摘要: |
| Potassium tetranitropalladate(II) was synthesized in one step by mixing palladium acetate and potassium nitrite in water with a yield of 96.5%. A single crystal of the product was cultivated using a solvent evaporation method, and was characterized by X-ray single crystal diffraction analysis. The crystal unit of the compound contains one centrosymmetric [Pd(NO2)4]2- complex anion, two K+ cations and two crystallized water molecules, belongs to triclinic crystal system and P-1 space group. The unit cell parameters are a=6.4953(5) nm, b=7.0134(5) nm, c=7.1473(5) nm, α=118.784(2)°, β=101.050(2)°, γ=98.085(2)°, Z=1. The Pd-N bond lengths are 2.014 and 2.037 nm, ∠N-Pd-N is 91.70(4)°, revealing that Pd2+ is in the center of the planar quadrilateral formed by four N atoms from the nitro groups. The cyclic voltammetry was measured at room temperature, and the reduction peak potential (Ep) was found to be -0.51 V (vs. SCE). |
