The irradiation of diborane(6) dispersed in solid neon at 3 K with tunable far-ultraviolet light from a synchrotron yielded a set of IR absorption lines, the pattern of which implies a carrier containing two boron atoms. According to isotope effects and quantum-chemical calculations, we identified this new species as diborane(4), BH, possessing two bridging B-H-B bonds. Our work thus establishes a new prototype, diborane(4), for bridging B-H-B bonds in molecular structures.
在3K温度下,用同步加速器产生的可调谐远紫外光照射分散在固体氖中的乙硼烷(6),得到了一组红外吸收线,其模式表明存在一种含有两个硼原子的载体。根据同位素效应和量子化学计算,我们将这种新物种鉴定为乙硼烷(4),BH,它具有两个桥连的B-H-B键。因此,我们的工作建立了一种新的分子结构中桥连B-H-B键的原型,即乙硼烷(4)。
