Broken Symmetry Group in the Octahedral [Me(urea)6]2+, 3+ Cation With Chelate Hydrogen Bonds

The work reports the study of broken symmetry groups of non-classical substitutions in real heterocomplex compounds with carbamide found in the description of cations with directed hydrogen bonds. Examples of the respective groups of products of non-classical substitutions are considered for the model structures. In the computer experiment, the examination of tables of binary transformations with broken symmetry discovered sets of transformations (“evolutionary trees”) with convergent and divergent properties of the structure orgraph that have not been previously studied.
