The authors show that the use of computer modeling in liquid copper exterior 3d-orbitals, due to the relative proximity to the nucleus and small extent, behave like pseudospherical. In addition, it has been a weak contraction of the interatomic distance, and the share of directed interactions increases. In the melt copper remains and prevalent the sequence of predominantly interatomic distances close to a densely packed crystallographic planes (111) FCC structure premelting. Significant redistribution of atoms between the coordination spheres, up to the disappearance of some of them, does not allow to consider the identified ordered microvolumes crystalline formations.
