在我们通过配体修饰来调节AgI配合物结构的努力中，6个结构相关的配体：1，2-双(三氮唑-1-甲基)苯(L1)，1，3-双(三唑-1-甲基)苯(L2)，1，4-双(三唑-1-甲基)苯(L3)，1，3，5-tri(triazol-1-ylmethyl)-2，4，6-trimethylbenzene(L4)，1，4-bis[3-(2-pyridyl)-pyrazol-1-ylmethyl]naphthalene(L5)，和9，10-二(苯并咪唑-1-甲基)菲(L6)与AgI盐反应生成六个新的配合物：{[Ag2(L1)2](BF4)2(H2O)}(1)，[Ag2(L2)(NO3)2]n(2)，[Ag(L3)(NO3)]n(3)，{[Ag3(L4)2](SiF6)1.5(H2O)3.5}(4)，{[AG2(L5)2](NO3)2(H2O)}(5)和{[AG2(L6)2](NO3)2(CH3OH)2}(6)。用红外光谱和X-射线衍射法对所有配合物进行了结构表征。结构分析表明，配合物1、5和6具有双核结构，由Ag-⋯N、C-H⋯O或π-π弱相互作用连接成无限配位网络。2是具有(10，3)-a拓扑的三维手性配位聚合物，4形成三核笼状结构，通过Ag⋯Ag弱相互作用进一步连接形成一维超分子，而3表现出无限的一维链结构。配合物1-6的结构从双核、三核、一维到三维网络，这表明配体在这种配位结构的形成中起着重要的作用。此外，还研究了手性络合物2的CD光谱、热性质和荧光性质。
In our efforts to tune the structures of AgI complexes by ligand modification, six structurally related ligands: 1,2-bis(triazol-1-ylmethyl)benzene (L1), 1,3-bis(triazol-1-ylmethyl)benzene (L2), 1,4-bis(triazol-1-ylmethyl)benzene (L3), 1,3,5-tri(triazol-1-ylmethyl)-2,4,6-trimethylbenzene (L4), 1,4-bis[3-(2-pyridyl)-pyrazol-1-ylmethyl]naphthalene (L5), and 9,10-bis(benzimidazol-1-ylmethyl)anthracene (L6) have been designed and used to react with AgI salts to form six new complexes: {[Ag2(L1)2](BF4)2(H2O)} (1), [Ag2(L2)(NO3)2]n (2), [Ag(L3)(NO3)]n (3), {[Ag3(L4)2](SiF6)1.5(H2O)3.5} (4), {[Ag2(L5)2](NO3)2(H2O)} (5), and {[Ag2(L6)2](NO3)2(CH3OH)2} (6). All the complexes have been structurally characterized by IR and X-ray diffraction. Structural analyses show that complexes 1, 5, and 6 possess dinuclear structures, which extend to infinite coordination networks linked by Ag⋯N, C–H⋯O, or π–π weak interactions. 2 is a 3D chiral coordination polymer with (10,3)-a topology, and 4 forms a trinuclear cage structure, which further connected by Ag⋯Ag weak interactions to form a 1D supramolecule, while 3 exhibits an infinite 1D chain structure. The structures of complexes 1–6 span from dinuclear, trinuclear, 1D, to 3D network, which indicates that ligands play important roles in the formation of such coordination architectures. Furthermore, the CD spectrum, thermal, and fluorescent properties of the chiral complex 2 have been investigated in the solid state.
