| 摘要: 以异烟酸(Hina)和2-磺基苯甲酸(H2L)为配体，在水热条件下与Y(Ⅲ)和Ag(Ⅰ)离子进行协同配位，合成了一个异金属配位聚合物[Y2Ag2L2(ina)4(H2O)2]n(1)。通过X-射线衍射、热重分析、元素分析和红外光谱对其进行表征。X-射线单晶衍射测定其结构为单斜晶系，P21/n空间群，晶胞参数a=0.914 43(3) nm，b=1.378 39(5) nm，c=1.760 76(5) nm，β=102.315(3)°，V=2.168 27(12) nm3，Z=4。它含有一个以羧基O原子桥连的中心对称的四核异金属原子簇[Y2Ag2L2]，相邻的原子簇之间通过异烟酸配体相互连接成三维金属有机骨架结构。 |

| Abstract: A heterometallic coordination polymer [Y2Ag2L2(ina)4(H2O)2]n (1) was synthesized by the synergistic coordination of isonicotinate(Hina) and 2-sulfobenzoate(H2L) ligands with Y(Ⅲ) and Ag(Ⅰ) ions under hydrothermal condition. It was characterized by single-crystal X-ray diffraction, powder XRD, thermogravimetric analysis, elemental analysis and infrared spectroscopy. Single-crystal X-ray diffraction reveals that it crystallizes in the P21/n space group. Unit cell parameters a=0.914 43(3) nm, b=1.378 39(5) nm, c=1.760 76(5) nm, β=102.315(3)°, V=2.168 27(12) nm3, Z=4. It contains a μ2-O bridged centrosymmetric heterometallic tetranulear cluster [Y2Ag2L2]. Adjacent tetranulear clusters are connected with each other through ina- ligands, forming a three-dimensional metal-organic framework. CCDC: 888050. |
