investigation of the structures of I and its isostructural analogs II and III (X-ray analysis, quantum-chemical calculations in the frame of DFT using NBO and QTAIM methods), data have been obtained on molecular interactions stabilizing DNIC dimer of µ–N–C–S structural type functionalized by 5-(2-nitrophenyl)-4-H-1,2,4-triazole-3-thiolyl. NBO calculations provided the assessment of bond energy for the Fe-S and
本工作旨在合成和研究一系列新的抗菌剂,即 [Fe 2 (SR) 2 (NO) 4 ] 组成的二亚硝基铁络合物 (DNIC) 二聚体,其中 R 为 5-(2-硝基苯基) -4- H -1,2,4-triazole-3-thiolyl ( I ), 5-(3-nitrophenyl)-4- H -1,2,4-triazole-3-thiolyl ( II ), 5-( 4-nitrophenyl)-4 - H -1,2,4-triazole-3-thiolyl ( III ),它们是一氧化氮 (NO) 供体,通过替换 [Fe(S 2 O 3 ) 2中的硫代硫酸盐配体很容易获得(NO) 2 ] 2-阴离子。基于对I及其同构类似物II和III的结构的研究(X 射线分析,使用 NBO 和 QTAIM 方法在 DFT 框架内进行的量子化学计算),获得了稳定 μ– 的 DNIC 二聚体的分子相互作用的数据由
