Abstract: The geometrically optimized structure of 43 new polymorphic varieties of L5-7α graphyne layers modeled on the basis of layers 5 – 7 of graphene has been calculated by the method of MM2 molecular mechanics. It was found that 3 polymorphic varieties of α type and 20 varieties of β and γ types are possible. The γ1 – L5-7α is the most stable layer since it has the minimal deformation parameter Def = 9,0°. Practical applications of new graphyne polymorphs can be used for molecular sieves or hydrogen adsorbents.
