Matrix Reactivity of AlF and AlCl in the Presence of HCl and HBr: Generation and Characterization of the New Al(III) Hydrides HAlFCl, HAlFBr, and HAlClBr and the Monomeric Mixed Al(III) Halides AlX<sub>2</sub>Y (X, Y = F, Cl, or Br)

presence of HCl and HBr in solid argon matrices were followed and the products identified and characterized by means of IR spectroscopy. Quantum mechanical calculations allow for a further evaluation of the properties of the reaction products. These are the adducts AlF.HCl, AlF.HBr, and AlCl.HBr, representing the products of spontaneous reactions, and the trivalent Al(III) hydrides HAlFCl, HAlFBr, and
跟踪在固体氩气中HCl和HBr存在下AlF和AlCl的自发和光解诱导反应,并通过红外光谱对产物进行鉴定和表征。量子力学计算可以进一步评估反应产物的性质。这些是自发反应的产物加合物AlF.HCl,AlF.HBr和AlCl.HBr,以及三价的Al(III)氢化物HAlFCl,HAlFBr和HAlClBr,它们是通过这些配合物的光活化而形成的。这三个氢化物都是平面分子(对称的C(s)()对称性),其键角与VSEPR理论的预测一致。此外,混合卤化物AlFCl(2),AlFBr(2)和AlClBr(2)在光解后形成。双加合物AlF。(HCl)(2)和AlF。
