Crystalline Self-Assembly of a Bowl-Like Cyclotriguaiacylene Derivative with Alcohol/Phenols by Hydrogen Bonding and C−H···π Interactions: The Self-Inclusion Extended Organic Frameworks

, 2010
Bowl-like tris-[(N-methyl-2-imidazolyl)methoxy]cyclotriguaiacylene (TMIM-CTG) (1) was synthesized and cocrystallized with ethanol, resorcinol, and phloroglucinol to afford three molecular complexes (TMIM-CTG)·(ethanol)3 (2), (TMIM-CTG)·(resorcinol ...

Quantification of binding affinities of essential sugars with a tryptophan analogue and the ubiquitous role of C-H···π interactions.

Physical Chemistry, Chemical Physics - PCCP, 2011
The role of noncovalent interactions in carbohydrate recognition by aromatic amino acids has long been reported. To develop a molecular understanding of noncovalent interactions in the recognition process, we have examined a series of binary complexes ...

C–H···π interactions inethynylbenzenes: the crystal structures of ethynylbenzene and1,3,5-triethynylbenzene, and a redetermination of the structure of1,4-diethynylbenzene

, 1997
The crystal structures of 1,4-diethynylbenzene 1 and 1,3,5-triethynylbenzene 2 show similar packing principles with CH···π (triple bond)-zigzag networks; surprisingly, the packing motif of ethynylbenzene 3 is quite different.

A supramolecular analog of cyclohexane sustained by aromatic C–H···π interactions between ferrocene moieties: molecular packing of ferrocene-containing thiosemicarbazato metal complexes

, 2000
Novel supramolecular cyclohexane-like structures, [NiL2] (1) and [ZnL2] (2) (HL=acetylferrocenyl thiosemicarbazone), have been constructed by self-assembly of ferrocene moieties ia aromatic C–H···π interactions.

Characterization of C-H...π interactions in the structure of the CHClF(2)-HCCH weakly bound complex.

Physical Chemistry, Chemical Physics - PCCP, 2010
The microwave spectra of four isotopologues of the CHClF(2)-HCCH dimer have been measured and used to determine the structure of the complex. An initial scan over the 7-18 GHz region using the chirped-pulse microwave spectrometer at the University of ...

C-H···π interactions in the CHBrF2···HCCH weakly bound dimer.

Journal of Physical Chemistry A, 2011
The microwave spectra of four isotopologues of the CHBrF(2)···HCCH weakly bound dimer have been measured in the 6-18 GHz region using chirped-pulse and Balle-Flygare Fourier-transform microwave spectroscopy.
