The crystal structure of 5,6,11,12,17,18-hexadehydro-1,4,7,10,13,16- hexaethynyltribenzo[a,e,i]cyclododecene tetrahydrofuran solvate: a case of high organization enforced by chelating alkyne C–H···O hydrogen bonding
Abstract
The crystal structure of the novel title dehydrobenzoannulene reveals supramolecular organization of the hydrocarbon around the occluded solvent molecules induced by novel multiple chelating alkyne C–H···O hydrogen bonds.
