在这里，我们讨论的反应产物的激光烧蚀碱金属氯化物和元素氯。盐烧蚀使用这种技术结合基质隔离光谱允许新的阴离子物种的形成和表征。激光烧蚀的固体MCl与M = Cs，Rb，和K的存在下的Cl 2产生游离[Cl 3]-离子被隔离在固体的贵气矩阵。当M = Cs、Rb、K和Na时，主要反应产物为离子对M+[Cl 3]-。将讨论在形成和键合的这些负离子的趋势。与三氟类似物相反，孤立的离子对M+[Cl 3]-由于金属配位而具有系统性畸变。
Here we discuss the reaction products of laser ablated alkali chlorides and elemental chlorine. Salt ablation using this technique combined with matrix-isolation spectroscopy allows for the formation and characterization of novel anionic species. The laser ablation of solid MCl with M = Cs, Rb, and K in the presence of Cl2 produced free [Cl3]- ions which were isolated in solid noble-gas matrices. For M = Cs, Rb, K, and Na, the ion pairs M+[Cl3]- are the main reaction products. Trends in the formation and bonding of these trichloride anions will be discussed. In contrast to the trifluoride analogues, the isolated ion pairs M+[Cl3]- feature a systematic distortion due to metal coordination.
