元素的结构特别美丽，因为它们的原子排列通常具有高度对称性。因此，发现新的修改收到相当大的关注远远超出了直接的研究领域。在这方面，最近最杰出的贡献之一是富勒烯的发现，它可以与金刚石和石墨一起作为碳的新变体。这项开创性的工作获得了诺贝尔奖，但正是在制备规模上生产富勒烯的能力使这一研究领域迅速扩大。[1，2]然而，在标准压力下发现其他元素的新晶体变体已经变得罕见;最近这些发现仅限于元素硫[3]和磷，其中红色纤维状磷的结构测定特别令人感兴趣。[4]美国
The structures of the elements are of particular beauty, owing to the usually high symmetry of their atomic arrangements. Therefore, the discovery of new modifications receives considerable attention far beyond the immediate field of research. One of the most outstanding recent contributions in this respect was the discovery of the fullerenes, which can be placed alongside diamond and graphite as new modifications of carbon. This pioneering work was awarded the Nobel Prize, but it was the capability to produce the fullerenes on a preparative scale that allowed the rapid expansion of this research area.[1, 2] However, the discovery of new crystalline modifications of other elements at standard pressure has become rare; such discoveries have recently been restricted to the elements sulfur [3] and phosphorous, with the structure determination of red fibrous phosphorous being of particular interest.[4]
