Special Issue Information

Dear Colleagues,

Undoubtedly, single-crystal X-ray diffraction (SCXRD) is one of the most powerful and robust techniques for solid-state structure determination. The properties of crystalline materials are related directly to their crystal structure. Crystallography provides the foundation for the understanding of the structure–properties relationship and connects the fundamental understanding of materials with their applications. The goal of this Special Issue of “Crystals” is expected to provide not only an excellent platform to report results that highlight the synthesis, characterization, and crystal structures of metal complexes, e.g., metal–organic and organometallic compounds but also the significant features of their structures such as interesting intra- and intermolecular interactions revealed by crystal structure analysis.

It is a pleasure to invite you to submit a manuscript for this Special Issue; regular articles, communications, and reviews are all welcome.

Magnesium aluminum alloy has a broad potential utilization because of its high specific stiffness, specific strength, excellent anti-vibration performance and good impact resistance. The main reason for the weakness of the welding strength of magnesium/aluminum as dissimilar metals during the welding process is the Mg23Al30 intermetallic compound. In the present article, first principle calculation methods are introduced to study the thermodynamic properties, structural stability, electronic structure, elastic properties and performance of Mg23Al30 under pressure. The decreasing range of c is greater than that of a, which indicates that the material has anisotropy. Mg and Al atoms in the Mg23Al30 structure are characterized by metal bonds. It can be concluded that Mg23Al30 not only behaves as a stable crystal structure but also has good elastic stability. After determined the ratio of the G/B criterion, Mg23Al30 belongs to the ductile materials. When treated with pressure in the range of 0–6 GPa, the volume modulus B, Young’s modulus E and shear modulus G of Mg23Al30 materials all increase with the pressure, which show its excellent mechanical stability.
