Abstract Reliable spectral criteria which allow comparison of the hydrogen and coordination bonds in isostructural systems are suggested. The model systems consist of ArXH and ArXMR n (X = O, S, N; M = Hg, Sn, Pb, Sb; Ar = C 6 H 4 Y where Y = COR, NO 2 , C 5 H 4 N, etc.) which interact with various N-, P- and O-bases. The conditions on which the ν XM vibrations are local, have been established. Examination
摘要 提出了可靠的光谱标准,可以比较同构系统中的氢键和配位键。模型系统包括 ArXH 和 ArXMR n(X = O、S、N;M = Hg、Sn、Pb、Sb;Ar = C 6 H 4 Y,其中 Y = COR、NO 2 、C 5 H 4 N 等.) 与各种 N-、P- 和 O-碱基相互作用。ν XM 振动是局部的条件已经建立。对硫醇衍生物的检查揭示了 ν XM 和 ν XH 区域中配位键和氢键的光谱(IR、拉曼)效应的相似性。质子和庞大的有机金属阳离子转移对介质、杂原子 X 或碱的依赖性特征显示为相似。发现了 XH 和 XM 键极性与形成复合物、离子对或离子的能力之间的一些定量和定性关系。
