| 摘要: 通过Cu(ClO4)2和丙二酸在水溶液中的自组装合成了一个新的3D配位聚合物：Na[Cu2(malonate)2]·(ClO4)·(H2O)2。X-射线结构分析表明该化合物晶体属于正交晶系Pnma空间群(a=1.256 5(3)，b=1.0594 3(2)，c=1.0755 6(14) nm，V=1.431 7(4) nm3，Z=4)。该聚合物的空间堆积在沿b轴和c轴方向分别形成大小为0.98 nm × 0.83 nm和0.40 nm × 0.40 nm的方形孔洞，在沿a轴方向形成大小为0.85 nm × 0.40 nm的砖墙形孔洞。磁性测试结果表明该化合物显示出铁磁性。导电性能测试实验表明它是一个半导体，经拟合得到其活化能为0.80 eV。 | |

| Abstract: A new 3D polymer, Na[Cu2(malonate)2]·(ClO4)·(H2O)2 was synthesized through the self-assembly of Cu(ClO4)2 and malonic acid in aqueous solution and characterized by X-ray structure analysis. The compound crystallizes in Orthorhombic, space group Pnma (a=1.256 5(3), b=1.059 43(2), c=1.075 56(14) nm, V=1.431 7(4) nm3, Z=4) and shows novel 0.98 nm × 0.83 nm and 0.40 nm× 0.40 nm square channels along the b and c directions, 0.85 nm × 0.40 nm “brick-wall” like channel along the a direction. Guest water molecules, Na+ and ClO4- ions are encapsulated in the channels of this 3D opening framework. The magnetic measurements reveal it exhibits ferromagnetic interaction. The electrical conductivity measurement reveals it is a semiconductor with active energy of 0.80 eV. CCDC: 247661. | |
