 lectrons in a kagome lattice can form a unique band structure characterize
 d by a flat band\, which\, if located near the Fermi level\, can lead to a
  large effective electron mass and exotic transport or magnetic properties
 . Among the candidates for such materials are intermetallic compounds with
  1:6:6 stoichiometry that crystallize in the hexagonal MgFe6Ge6-type struc
 ture. The talk is devoted to the experimentally observed off-stoichiometry
  and structural disorder effects that occur in some of these compounds\, i
 n particular\, the isotypic series RCr6Ge6 (R — rare-earth element). The
  peculiarities of the chemical bonding in these compounds revealed by DFT 
 modeling are compared to the simple crystal chemistry considerations to un
 derstand the origin of the disorder and their properties better. A compari
 son with other isotypic series is performed to show some common structural
  and bonding features.</p>  <p><strong>BigBlueButton:</strong> https://bbb
