Abstract: Abstract Two-dimensional self-assemblies of four partially fluorinated molecules, 1,4-bis(2,6-difluoropyridin-4-yl)benzene, 4,4′-bis(2,6-difluoropyridin-4-yl)-1,1′-biphenyl, 4,4′-bis(2,6-difluoropyridin-4-yl)-1,1′:4′,1″-terphenyl and 4,4′-bis(2,6-difluoropyridin-3-yl)-1,1′-biphenyl, involving weak intermolecular C H⋯F and C H⋯N hydrogen bonds were systematically investigated on Au(111) with low-temperature scanning tunneling microscopy. The inter-molecular… read more here.

Abstract: Primary weak hydrogen bonds in each of three independent molecules in 3,4-bis-O-propargyl-1,2:5,6-di-O-isopropylidene-d-mannitol are elucidated by single-crystal X-ray diffraction and their importance in molecular conformation and crystal packing determined. Parallel searches of the Cambridge Structural Database… read more here.
