- Аннотация: Ordered intermetallic compounds are one of the most fascinating objects in inorganic chemistry, their very existence challenging classical concepts of metallic bond and its directionality, or lack thereof. The variety of crystal structures arising from different combinations of metals is simply amazing, with 2166 structure types and just under 21000 unique ordered intermetallics (excluding solid solutions and statistical alloys) characterized by 2015, and yet the field is still considered practically unexplored. One of the most common structure types among intermetallics is the AuCu¬3 type. It is derived from the copper structure type and is a primitive cubic structure with coordination number of 12 for each metal. Thus, the structural unit in AuCu3 is a cuboctahedron, e.g. gold-centered copper cuboctahedron [Cu12Au]. In our work, we try to use cuboctahedra based on Group 10 metals (Ni, Pd, Pt) as building blocks for the structures of varying complexity, either by diluting 3D metallic system with a nonmetal (such as chalcogens or pnicogens), or by specifically designing new linear intergrowth structures. In this report we showcase several structure types and motifs arising from such approach.
