在单核化合物[Zn(C9H7N7)(C10H4O8)(H2O)3]·3H2O中,Zn(II)金属中心离子分别和4个氧和2个氮原子配位,其中4个氧原子来自于一个去质子的均四苯甲酸(H2BTCA)和3个配位水分子,氮原子来自5-(2-吡啶基)-3,3’-联(1H-1,2,4-三氮唑)(H2pbt)配体.在这个结构中,相邻的单核单元之间通过分子内和分子间的O-H···O和NH···O氢键作用连接成二维超分子结构,且三唑环与苯环之间以及相邻吡啶环之间存在芳香堆积作用.此外,还研究了标题配合物的固态荧光性质.
In the mononuclear compound [Zn (C9H7N7) (C10H4O8) (H2O) 3] · 3H2O, Zn (II) metal centers coordinate to 4 oxygen and 2 nitrogen atoms, respectively, of which 4 oxygen atoms come from one (H2BTCA) and three coordination water molecules, the nitrogen atom is derived from 5- (2-pyridyl) -3,3’-bis (1H- 1,2,4- triazole) (H2pbt ) Ligand.In this structure, adjacent mononuclear units are connected into two-dimensional supramolecular structure through intramolecular and intermolecular OH ··· O and NH ··· O hydrogen bonds, and the triazole ring With the aromatic ring between the benzene ring and the adjacent pyridine ring.In addition, the solid-state fluorescence properties of the title complex were also studied.
