摘要: 3,6-二(2-(4-氧化苯并吡嗪基))-4,5-二氮杂-3,5-辛二烯配体(L)与银盐室温下反应得到了2个结构新颖的离散型配位化合物[Ag8(L)8](BF4)8·CH2Cl2·3CH3OH(1)和[Ag4(L)4](PF6)4·CH2Cl2(2)。通过红外、元素分析、X射线单晶衍射等检测手段对所得配合物进行了表征。结果表明,2个配合物皆以二聚体的形式存在。未配位的平衡阴离子与二聚体通过氢键连接成一维或二维结构。 |

Abstract: Two novel discrete complexes with Ag(Ⅰ) centers based on the double Schiff-base ligand, 3,6-bis(2-(4-oxide-quinoxaline)-yl)-4,5-diaza-3,5-octadiene (L), have been synthesized. The obtained Ag(Ⅰ) complexes,[Ag8(L)8](BF4)8·CH2Cl2·3CH3OH (1) and[Ag4(L)4](PF6)4·CH2Cl2 (2), were fully characterized by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction. Both complexes exist as dimers. Through hydrogen bonds, uncoordinated counter ions and discrete molecular complex building blocks formed one-dimensional (1D) or two-dimensional (2D) frameworks. |
Keywords: double Schiff-base ligand discrete compound hydrogen bond |
