  • X-ray crystal structure of trans -bis(pyridin-3-yl)ethylene: comparing the supramolecular structural features among the symmetrical bis( n -pyridyl)ethylenes ( n = 2, 3, or 4) constitutional isomers
Title: X-ray crystal structure of trans -bis(pyridin-3-yl)ethylene: comparing the supramolecular structural features among the symmetrical bis( n -pyridyl)ethylenes ( n = 2, 3, or 4) constitutional isomers
The molecular structure of trans -bis(pyridin-3-yl)ethylene ( 3,3′-bpe ), C 12 H 10 N 2 , as determined by single-crystal X-ray diffraction is reported. The molecule self-assembles into two dimensional arrays by a combination of C—H...N hydrogen bonds and edge-to-face C—H... π interactions that stack in a herringbone arrangement perpendicular to the crystallographic c -axis. The supramolecular forces that direct the packing of 3,3′-bpe as well as its packing assembly within the crystal are also compared to those observed within the structures of the other symmetrical isomers trans -1,2-bis( n -pyridyl)ethylene ( n , n ′-bpe , where n = n ′ = 2 or 4).  more » « less

    The formation of a photoreactive cocrystal based upon 1,2-diiodoperchlorobenzene ( 1,2-C 6 I 2 Cl 4 ) and trans -1,2-bis(pyridin-4-yl)ethylene ( BPE ) has been achieved. The resulting cocrystal, 2( 1,2-C 6 I 2 Cl 4 )·( BPE ) or C 6 Cl 4 I 2 ·0.5C 12 H 10 N 2 , comprises planar sheets of the components held together by the combination of I...N halogen bonds and halogen–halogen contacts. Notably, the 1,2-C 6 I 2 Cl 4 molecules π-stack in a homogeneous and face-to-face orientation that results in an infinite column of the halogen-bond donor. As a consequence of this stacking arrangement and I...N halogen bonds, molecules of BPE also stack in this type of pattern. In particular, neighbouring ethylene groups in BPE are found to be parallel and within the accepted distance for a photoreaction. Upon exposure to ultraviolet light, the cocrystal undergoes a solid-state [2 + 2] cycloaddition reaction that produces rctt -tetrakis(pyridin-4-yl)cyclobutane ( TPCB ) with an overall yield of 89%. A solvent-free approach utilizing dry vortex grinding of the components also resulted in a photoreactive material with a similar yield.

    Abstract Cocrystallizations of diboronic acids [1,3‐benzenediboronic acid (1,3‐bdba), 1,4‐benzenediboronic acid (1,4‐bdba) and 4,4’‐biphenyldiboronic acid (4,4’‐bphdba)] and bipyridines [1,2‐bis(4‐pyridyl)ethylene (bpe) and 1,2‐bis(4‐pyridyl)ethane (bpeta)] generated the hydrogen‐bonded 1 : 2 cocrystals [(1,4‐bdba)(bpe)2] (1), [(1,4‐bdba)(bpeta)2] (2), [(1,3‐bdba)(bpe)2(H2O)2] (3) and [(1,3‐bdba)(bpeta)2(H2O)] (4), wherein 1,3‐bdba involved hydrated assemblies. The linear extended 4,4’‐bphdba exhibited the formation of 1 : 1 cocrystals [(4,4'‐bphdba)(bpe)] (5) and [(4,4'‐bphdba‐me)(bpeta)] (6). For 6, a hemiester was generated by an in‐situ linker transformation. Single‐crystal X‐ray diffraction revealed all structures to be sustained by B(O)−H⋅⋅⋅N, B(O)−H⋅⋅⋅O, Ow−H⋅⋅⋅O, Ow−H⋅⋅⋅N, C−H⋅⋅⋅O, C−H⋅⋅⋅N, π⋅⋅⋅π, and C−H⋅⋅⋅π interactions. The cocrystals comprise 1D, 2D, and 3D hydrogen‐bonded frameworks with components that display reactivities upon cocrystal formation and within the solids. In 1 and 3, the C=C bonds of the bpe molecules undergo a [2+2] photodimerization. UV radiation of each compound resulted in quantitative conversion of bpe into cyclobutane tpcb. The reactivity involving 1 occurred via 1D‐to‐2D single‐crystal‐to‐single‐crystal (SCSC) transformation. Our work supports the feasibility of the diboronic acids as formidable structural and reactivity building blocks for cocrystal construction.

    N -Butyl-2,3-bis(dicyclohexylamino)cyclopropenimine ( 1 ) crystallizes from benzene and hexanes in the presence of HCl as a monobenzene solvate of the hydrochloride salt, [ 1 H]Cl·C 6 H 6 or C 31 H 54 N 3 + ·Cl − ·C 6 H 6 , in the P 2 1 / n space group. The protonation of 1 results in the generation of an aromatic structure based upon the delocalization of the cyclopropene double bond around the cyclopropene ring, giving three intermediate C—C bond lengths of ∼1.41 Å, and the delocalization of the imine-type C—N double bond, giving three intermediate C—N bond lengths of ∼1.32 Å. Ion–ion and ion–benzene packing interactions are described and illustrated.

    Structural characterization of the ionic complexes [FeCl 2 (C 26 H 22 P 2 ) 2 ][FeCl 4 ]·0.59CH 2 Cl 2 or [(dppen) 2 FeCl 2 ][FeCl 4 ]·0.59CH 2 Cl 2 (dppen = cis -1,2-bis(diphenylphosphane)ethylene, P 2 C 26 H 22 ) and [FeCl 2 (C 30 H 24 P 2 ) 2 ][FeCl 4 ]·CH 2 Cl 2 or [(dpbz) 2 FeCl 2 ][FeCl 4 ]·CH 2 Cl 2 (dpbz = 1,2-bis(diphenylphosphane)benzene, P 2 C 30 H 24 ) demonstrates trans coordination of two bidentate phosphane ligands (bisphosphanes) to a single iron(III) center, resulting in six-coordinate cationic complexes that are balanced in charge by tetrachloridoferrate(III) monoanions. The trans bisphosphane coordination is consistent will all previously reported molecular structures of six coordinate iron(III) complex cations with a (PP) 2 X 2 ( X = halido) donor set. The complex with dppen crystallizes in the centrosymmetric space group C 2/ c as a partial-occupancy [0.592 (4)] dichloromethane solvate, while the dpbz-ligated complex crystallizes in the triclinic space group P 1 as a full dichloromethane monosolvate. Furthermore, the crystal studied of [(dpbz) 2 FeCl 2 ][FeCl 4 ]·CH 2 Cl 2 was an inversion twin, whose component mass ratio refined to 0.76 (3):0.24 (3). Beyond a few very weak C—H...Cl and C—H...π interactions, there are no significant supramolecular features in either structure.

    We describe hydrogen bonds ( i.e. , N + –H⋯N) in combination with cation⋯π interactions to enable a cascade-like [2 + 2] photodimerization of 4-stilbazole in a salt cocrystal. A four-component crystal assembly is composed of photoactive pyridinium ion pair 4-stilbzH + ( 4-stilbz = trans -1-(4-pyridyl)-2-(phenyl)ethylene) and photostable molecule pair 4-stilbz . UV irradiation gives rctt -1,2-bis(4-pyridyl)-3,4-bis(phenyl)cyclobutane ( 4-pyr-ph-cb ) in quantitative yield. An intermediate structure 2 ( 4-stilbz )·( 4-pyr-ph-cb )2H + is isolated that undergoes a partial single-crystal-to-single-crystal transformation. The single-crystal X-ray data provides a snapshot of movements in the salt cocrystal in the course of the photodimerization.
