International think-tank, including researchers from Russia, Italy, China and USA, synthesized a substance, which behaves like it contains several elements, but in fact, consists of only one.
      
      New substance is boride of boron. Its chemical formula is B₂₈, and it lives under very high pressure and temperature – over 190 thousand atmospheres and 1400 degrees Centigrade.
      
      All atoms in known large molecules, made from one element – fullerenes, for instance – are equal, but this is not the case. B₂₈ has two different from each other structural units: icosahedral cluster B₁₂ and cluster B₂, which form a crystal lattice, similar to that of sodium chloride. One lattice cell contains 28 atoms of boron, that is why the compound has B₂₈ formula.
      
      New state of boron is called “partially ionized”, since two clusters have different electronic properties, and charge is transferred between them like between two different elements.
