Crystal structure and Hirshfeld surface analysis of 1,3-diethynyladamantane.
Ontology highlight
ABSTRACT: The title compound, C14H16, exhibits exceptionally weak inter-molecular C-H⋯π hydrogen bonding of the ethynyl groups, with the corresponding H⋯π separations [2.91 (2) and 3.12 (2) Å] exceeding normal vdW distances. This bonding complements distal contacts of the CH (aliphatic)⋯π type [H⋯π = 3.12 (2)-3.14 (2) Å] to sustain supra-molecular layers. Hirshfeld surface analysis of the title compound suggests a relatively limited significance of the C⋯H/H⋯C contacts to the crystal packing (24.6%) and a major contribution from H⋯H contacts accounting 74.9% to the entire surface.
