- Аннотация: There does exist a relationship with “saturation” of the X···X (X= H, F, CH3, CN, Cl, Br, I) distances in the series Be to Ra compounds. The X···X distances remain practically constant after the M-X distance has increased beyond a certain extent: for each kind of ligand pair, X2, these limiting distances are found to be 4.030.08, 4.050.08, 4.70.1, 4.90.1, 5.150.1, 5.60.1, and 6.20.1 Å respectively. The acceptance of this rule of limiting distances allows for some semi-empirical tests to estimate the linear/bent structures of triatomic molecules. The switch of Dh C2v symmetry of MX2 is explained by involving the bonded Rydberg-like orbital of two negatively charged X moieties (X = hydride, halide, cyanide and methyl ligands).
