- - The study of Be Ru's hexagonal layered crystal structure utilized single crystal X-ray diffraction and transmission electron microscopy, revealing a main hexagonal matrix with minor orthorhombic inclusions.
- - The atomic arrangement is stabilized through charge transfer from Be to Ru and the presence of polar three- and four-atomic bonds between the elements.
- - Unlike typical intermetallic compounds, Be Ru displays a pseudo gap in its electronic density of states near the Fermi level, and it demonstrates metallic behavior in electrical resistivity as a result of a non-zero DOS at that level.
MgPt represents the family of complex intermetallic compounds (complex metallic alloys, CMAs). It crystallizes in the cubic non-centrosymmetric space group 4̅3 with = 20.1068(2) Å and around 400 atoms in a predominantly ordered arrangement.

- The Be Ru phase has a TiCu-type crystal structure, characterized by specific dimensions (a=3.7062 Å, b=4.5353 Å, c=4.4170 Å) and is a variant of hexagonal closest packing (hcp) of spheres.
- Its electronic structure shows a pseudo-gap near the Fermi level, with notable charge transfer from beryllium (Be) to ruthenium (Ru) identified through Quantum Theory of Atoms in Molecules (QTAIM) analysis.
- Unlike typical inorganic compounds, Be Ru displays an unusual feature where different charged species coexist within the same packing arrangement, and it is characterized as a diamagnet with metallic electrical resistivity.
The high incidence of the resistance phenomenon represents one of the most important limitations to the clinical usefulness of cisplatin as an anticancer drug. Notwithstanding the considerable efforts to solve this problem, the circumvention of cisplatin resistance remains a challenge in the treatment of cancer. In this work, the synthesis and characterization of two -dichloro(triphenylarsino)(,-dialkylamino)platinum(II) complexes ( and ) were described.
