tert‑butylamine. The results unveil that among all the studied crystals the NH2 in L are protonated when the acids are deprotonated, the crystal packing is interpreted via the strong NH⋯O H-bond from the NH3+ and the deprotonated acids. Apart from the NH⋯O H-bond, the OH···O H-bonds were also existed at 6 and 12. Salts 1 - 2 had the NH⋯S H-bond. The NH···Cl H-bond existed in 7. Further view of the crystal packing
广泛使用的最简单的大量伯胺叔丁胺与一组酸共结晶得到总共 14 种盐,这些盐已通过 XRD 技术、红外光谱和元素分析进行表征。还调查了它们的熔点。详细分析了它们的结构和超分子方面。所有化合物都是离子型的,H 会转移到叔丁胺的 NH 2上。结果表明,在所有研究的晶体中,当酸去质子化时,L 中的 NH 2被质子化,晶体堆积是通过来自 NH 3 +和去质子化酸的强 N H⋯O H 键来解释的。除了 NH⋯O H-bond,O H...O H-bonds也存在于6和12。盐1 - 2具有 N H⋯S H 键。N H···Cl H-键存在于7 . 晶体堆积的进一步观察表明,不同阵列的附加 CH 3 ...S, O...Cl, S...S, CH 3 ...C, CH 3 ...CH 3 , C H· ··O/CH 3 ···O, CH 2 ···Cl, CH···N, CH 3···π和π···π
