碱金属-金化合物过去称为合金,现在一般称为金属间化合物(intermetallics),其性质随各相内碱金属/金比例及碱金属原子序数递增而有规律地变化.但无论如何,它们溶解于液氨及1,2,-二氨基乙烷中及它们形成(2,2,2-crypt.-M~+)An~-(M=K,Rb,Cs)络合物的电化学,穆斯堡尔谱学及光电子能谱研究已经说明其中金形成了阴离子(Au~-).金属间化合物中RbAu和CsAu为CsCl型立方晶体结构,具离子性,已证明有相当强的电子密度从 Alkali-gold compounds, formerly known as alloys, are now commonly referred to as intermetallics and their properties change regularly with increasing ratios of alkali metals / gold and alkali metal atoms within each phase, but in any case they dissolve In liquid ammonia and 1,2-diaminoethane and their formation of (2,2,2-crypt.-M ~ +) An ~ (M = K, Rb, Cs) Mossbauer spectroscopy and photoelectron spectroscopy studies have shown that gold forms anions (Au ~). Among the intermetallic compounds, RbAu and CsAu are CsCl-type cubic structures with ionicity and have been shown to have fairly strong electron densities From
