The title mol-ecule, CHF, crystallizes in the monoclinic space group 2/ with two unique mol-ecules in the asymmetric unit and = 8. Each mol-ecule features a short intra-molecular -C-H⋯F hydrogen...

The cocrystallization of the ditopic halogen bond donors 2,5-, 2,6-, 3,5-bis(iodoethynyl)pyridines with the dipyrimidyls 1,2-bis(5-pyrimidyl)ethyne and 1,4-bis(5-pyrimidyl)butadiyne is explored. The cocrystal components have complementary shapes and functional groups so that...

The structures of a series of 2:1 cocrystals formed between 4-(dimethylamino)pyridine and each of 1,2,4,5-tetrachloro-3,6-diiodobenzene, 2CHN·CClI, 1,2,4,5-tetrabromo-3,6-diiodobenzene, 2CHN·CBrI, 1-bromo-4-iodo-2,3,5,6-tetrafluorobenzene, 2CHN·CBrFI, and 1,2-dibromo-4,5-difluoro-3,6-diiodobenzene, 2CHN·CBrFI, are reported. In all five structures, the...

The formation of supramolecular parallelograms utilizing iodoalkyne-pyridine halogen bonding is described. The crystal structures of four iodoalkynyl-substituted (phenylethynyl)pyridines demonstrate the feasibility of discrete self-complementary dimer formation. These compounds 3-(2-iodoethynyl-phenylethynyl) pyridine...

Macrocycle formation that relies upon trans metal coordination of appropriately placed pyridine ligands within an arylene ethynylene construct provides rapid and reliable access to molecular rotators encapsulated within macrocyclic stators....

The present study evaluates the potential combination of charge-transfer electron-donor-acceptor π-π complexation and C-H hydrogen bonding to form colored cocrystals. The crystal structures of the red 1:1 cocrystals formed from...

The treatment of 5-{[4-(di-methyl-amino)-phen-yl]ethyn-yl}pyrimidine with a threefold excess of 1,2,3,5-tetra-fluoro-4,6-di-iodo-benzene in di-chloro-methane solution led to the formation of the unexpected 1:2 title co-crystal, CHN·2CFI. In the extended structure, two unique...

1,3-Diiodo-5-nitrobenzene, CHINO, and 1,3-dibromo-5-nitrobenzene, CHBrNO, crystallize in the centrosymmetric space group P2/m, and are isostructural with 1,3-dichloro-5-nitrobenzene, CHClNO, that has been redetermined at 100 K for consistency. While the three-dimensional...

The rapid evaporation of 1:1 solutions of diethynylpyridines and N-halosuccinimides, that react together to form haloalkynes, led to the isolation of unreacted 1:1 cocrystals of the two components. The 1:1...

This study expands and combines concepts from two of our earlier studies. One study reported the complementary halogen bonding and π-π charge transfer complexation observed between isomeric electron rich 4-,-dimethylaminophenylethynylpyridines...
