Graphyne is a crystalline form of carbon that is distinct from both diamond and graphite. Unlike diamond, where each atom possesses four immediate neighbors, or graphite, where each atom has three, graphyne's structure combines two-coordinate and three-coordinate carbons.
This article has been reviewed according to Science X's editorial process and policies . Editors have highlighted the following attributes while ensuring the content's credibility: Orthogonal to sheet plane views of AA, AB1, AB2, and ABC stacking arrangements for graphyne. Only the AA and AB1 packing modes are consistent with the interplanar reaction of triple bonds to form polyacetylene chains in reacted graphyne.
