In this article, the former system of calculation has been replaced by a new one proposed by E.S. Fedorov. Anyone who has made use of crystallographic literature, even revised works such as Groth's "Chemical crystallography", knows how inconsistent and often the completely confusing the data can be, making it impossible to construct a diagram, and therefore, to make use of the author's research efforts. Such complete inability to reconstruct the crystal complex led to the creation of a new system of calculations using bipolar coordinates, which, with the slightest misunderstanding in the data angles, can restore reality.
