| 摘要: 通过M(NO3)2(M=Zn，Cd)和二(3，5-二甲基吡唑)甲烷(dmpzm)的反应，合成了2个锌和镉配合物[M(dmpzm)2(NO3)][NO3](1：M=Zn；2：M=Cd)。配合物1和2经元素分析,红外光谱表征，并经X射线单晶衍射法证实。配合物1属于正交晶系，空间群为Pca21，晶体学参数：a=1.625 9(3) nm，b=0.832 10(17) nm，c=2.031 1(4) nm，V=2.747 9(10) nm3，Z=4。配合物2属于正交晶系，空间群为Pca21，晶体学参数：a=1.674 36(15) nm，b=0.821 29(7) nm，c=2.048 01(19) nm，V=2.816 3(4) nm3，Z=4。在这2个配合物的阳离子中，金属原子分别与2个dmpzm中的4个N原子及1个NO3-中的2个O原子配位，形成略为畸变的八面体构型。配合物1和2的晶体中，NO3-的O原子与配体dmpzm中的甲基及亚甲基间存在的C-H…O氢键作用，从而形成了有趣的三维网状结构。此外，还研究了配合物1和2的荧光性质。 |

| Abstract: Reactions of M(NO3)2 (M=Zn, Cd) with bis(3,5-dimethylpyrazol-1-yl)methane (dmpzm) formed two mononuclear compounds [M(dmpzm)2(NO3)][NO3] (1: M=Zn; 2: M=Cd). Both 1 and 2 were characterized by elementary analysis, IR, and their crystal structures were determined by X-ray single crystal structural analysis. In the cations of 1 and 2, the metal center is coordinated by four N atoms of the two dmpzm ligands and two O atoms from a NO3- anion, forming a distorted octahedral geometry. The interactions between oxygen atoms of the nitrates and the methylene and methyl groups afforded lots of C-H…O hydrogen bonds, thereby forming an interesting 3D hydrogen-bonded network in the crystal of 1 or 2. Their photoluminescent properties were also studied. CCDC: 294219, 1; 294221, 2. |
