在多元无机化合物中,有一类由金属—半金属—非金属组成的化合物,其通式可写作A_mB_nS_p,式中A表示金属,B为周期表中第V族元素As、Sb及Bi,S为非金属。这类化合物中因具有BS_3基团,为有别于硫化物及硫酸盐,故命名为“硫盐”。自然界以矿物形式存在的硫盐有百余种,然而人工合成的尚不多见。业已发现由不同金属组成的硫盐具有独特的半导体、超导体、超磁及光学性质,因此,对这类化合物的研究,
Among the multivariate inorganic compounds, there is a class of compounds consisting of metal-semimetal-nonmetal, the general formula can be written as A_mB_nS_p, where A is the metal, B is the group V elements As, Sb and Bi of the periodic table, S is Non-metallic. Because of these compounds have BS_3 group, as distinct from the sulfide and sulfate, so named “sulfur salt.” There are over 100 kinds of sulfur salts in nature in the form of minerals, however, artificial synthesis is rare. It has been found that sulfur salts composed of different metals have unique semiconducting, superconducting, super-magnetic and optical properties. Therefore, the research on such compounds,
