摘要

以锰改性的线性子结构为例，我们展示了四面体沿其侧面组装形成的两种螺旋，即四个四面体的七顶点联盟。我们还讨论了证实金属纳米线结构中存在这种螺旋堆积的实验数据。四面体螺旋堆积的非晶对称性使我们能够充分描述密集堆积金属中也存在的晶体和非晶四面体结构。

Spiral Substructures of Nanowires Determined by the Universal Building Unit (Tetrablock)

On the example of linear substructures of Mn modifications, we show two types of spirals formed by tetrablocks assembled along their sides, namely, seven-vertex unions of four tetrahedra. Experimental data that confirm the existence of spiral packings of this kind in the structures of metallic nanowires are discussed. The noncrystallographic symmetry of the spiral packing of tetrablocks enables us to adequately describe the crystalline and noncrystalline tetrahedral structures that are also present in densely packed metals.
