摘要: 2D and 3D lattice complexes with increased self-coordination numbers Τ i =1-3, of nearest, second third neighbors were derived for characteristic Wyckoff sets zero or one parameters. Structure types adsorbedatoms in elements A x B y , compounds are approximated to the list complexes. Covalent bonding electronic effects atoms like lone electron pairs Jahn-Teller distortion give rise deviations from Homogeneous structures identical A-A B-B T 1 2 3 next-nearest selected different systems magnetic ordering = ⊕ ⊖ spin direction crystals organic molecules orientations.
