Here two compds. with a central 1,4-disubstituted 1,2,3-triazole ring are synthesized to investigate the electronic bridging between terminal stilbazole and pyridine groups in the cryst. phase.  The electronic properties of the mols. are characterized through soln. phase UV-vis spectroscopy, single crystal X-ray diffractions, and d.-of-state and gas-phase DFT calcns.  We show that the electronic bridging behavior of a 1,4-disubstituted 1,2,3-triazole ring derived from a click reaction is maintained in the solid state by rare head-to-head (hh) packing in noncentrosym. crystal environments.

	abstract = {Treatment of an achiral mol. ladder of C2h symmetry composed of five edge-sharing cyclobutane rings, or a [5]-ladderane, with acid results in cis- to trans-isomerization of end pyridyl groups.  Soln. NMR spectroscopy and quantum chem. calcns. support the isomerization to generate two diastereomers.  The NMR data, however, could not lead to unambiguous configurational assignments of the two isomers.  Single-crystal X-ray diffraction was employed to det. each configuration.  One isomer readily crystd. as a pure form and X-ray diffraction revealed the mol. as being achiral based on Ci symmetry.  The second isomer resisted crystn. under a variety of conditions.  Consequently, a strategy based on a cocrystn. was developed to generate single crystals of the second isomer.  Cocrystn. of the isomer with a carboxylic acid readily afforded single crystals that confirmed a chiral ladderane based on C2 symmetry.  The chiral ladderane and acid self-assembled to generate a five-component hydrogen-bonded complex that packs to form large solvent-filled homochiral channels of nanometer-scale dimensions.  Whereas cocrystns. are frequently applied to structure detns. of proteins, our study represents the first application of a cocrystn. to confirm the relative configuration of a small-mol. diastereomer generated in a soln.-phase org. synthesis.

The co-crystal was discovered by screening using the soln.-mediated phase transformation (SMPT) technique.  Despite the bulk solids of each component being white in color, the new co-crystal phase exhibited a red color.  The new phase was analyzed using single-crystal X-ray diffraction and identified as (APAP){\textperiodcentered}(PDA){\textperiodcentered}(1).  Structural anal. revealed PDA to exist in a hitherto unreported zwitterionic form in the co-crystal.  A structural anal. of pure PDA revealed the presence of the zwitterion form in (PDA){\textperiodcentered}(H2O) (2), as well.  The components of 1 self-assemble as a three-dimensional (3D) hydrogen-bonded network with a pronounced 2D structure.
