合成了2个含有吡啶基苯甲酸盐的银(Ⅰ)配合物,即[Ag_2(PPh_3)_2(4,4-pybz)_2(H_2O)_2]_n(1)和[Ag_2(PPh_3)_2(4,3-pybz)_2]·2CH_3OH(2)(PPh_3=三苯基膦,4,4-pybz=4-吡啶-4-基-苯甲酸根,4,3-pybz=4-吡啶-3-基-苯甲酸根),并通过红外光谱、元素分析和荧光光谱进行分析和表征,它们的结构由X射线单晶衍射测定。在不同的溶剂下,2个配合物由AgBF_4、PPh_3和不同的吡啶苯甲酸在氨水作用下,以1∶1∶1的比例反应而成。在配合物1中,所有的银原子由吡啶基苯甲酸桥连形成一维链状结构。在配合物2中,2个银原子通过2个4-吡啶-3-基-苯甲酸根配体形成双核结构。在荧光光谱中,在发射状态下所有的峰均来源于配体的π-π*跃迁。
Two silver (Ⅰ) complexes containing pyridylbenzoate were synthesized, namely [Ag_2 (PPh_3) _2 (4,4-pybz) _2 (H_2O) _2] _n (1) and [Ag_2 (PPh_3) _2 (4,3-pybz) _2] .2CH_3OH (PPh_3 = triphenylphosphine, 4,4-pybz = 4-pyridin- 3-yl-benzoate) and analyzed and characterized by infrared spectroscopy, elemental analysis and fluorescence spectroscopy, and their structures were determined by X-ray single crystal diffraction. Under different solvents, two complexes were formed by the reaction of AgBF_4, PPh_3 and different picolinic acids in the ratio of 1: 1: 1. In complex 1, all the silver atoms were bridged by pyridylbenzoic acid to form a one-dimensional chain structure. In complex 2, two silver atoms form a dinuclear structure via two 4-pyridin-3-yl-benzoate ligands. In the fluorescence spectrum, all the peaks in the emission state are derived from the π-π * transition of the ligand.
