摘要: 以1-(4-咪唑基)-4-(四氮唑)苯(HL)与对苯二甲酸(H2pbda)或间苯二甲酸(H2mbda)作为混合配体,与硫酸锌进行水热合成反应,构筑了2个新的金属配位配合物[Zn2(L)2(pbda)]n (1)和[Zn2(L)2(mbda)]n (2),并进行了元素分析、红外、热重、X射线粉末衍射及单晶衍射等表征。晶体结构分析表明:配合物1结构中,去质子化的L-与锌离子结合成[Zn2(L)2]2+的二维结构,相邻的二维层由pbda2-配体连接成二重贯穿层柱状的具有dmc拓扑的三维结构,拓扑符号为(4·82)(4·85);配合物2是由2个羧酸基团与锌离子形成的双核[Zn2(COO)2]为基本单元连结而成的单一6连结具有(412·63)-pcu拓扑的三维结构。同时,对配合物1和2在室温下的固体荧光性质进行了研究。 |

Abstract: Two Zn (Ⅱ)coordination polymers[Zn2 (L)2 (pbda)]n (1)and[Zn2 (L)2 (mbda)]n (2)were synthesized by reactions of ZnSO4·7H2O with rigid ligand 1-(1H-imidazol-4-yl)-4-(4H-tetrazol-5-yl)benzene (HL)and different carboxylic acids of 1,4-benzenedicarboxylic acid (H2pbda)or 1,3-benzenedicarboxylic acid (H2mbda). The complexes have characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy, photolu-minescence spectrum, TG and PXRD. Polymer 1 possesses[Zn2 (L)2]2+ sheets pillared by the pbda2- ligand to form a 2-fold interpenetrating three-dimensional (3D)dmc net with point Schläfli symbol of (4·82) (4·85), while 2 exhibits a uninodal 6-connected 3D architecture with (412·63)-pcu topology based on the binuclear Zn (Ⅱ)secondary building units (SBUs). Solid state luminescent properties of 1 and 2 have been investigated. CCDC:1502275, 1; 1502276, 2. |
