A novel activated prochiral ketoimine, (E)-acetophenoneO-diphenylphosphoryl oxime, C20H18NO2P, with an electron-withdrawing substituent on the imine N atom similar to other prochiral ketoimines, has been synthesized and the X-ray crystal stucture determined. The molecules pack together in the solid stateviaweak intermolecular C—H...O interactions and both face-to-face and edge-to-face π-stacking interactions.

Good electrical bistability performances in stilbazolium/iodocuprate hybrids stem from the better face-to-face π⋯π stacking interactions induced by the substituents with appropriate lengths and electronic natures.

AbstractThe complex [Ir(ppy)2(dpbpy)][PF6] (Hppy = 2-phenylpyridine, dpbpy = 6,6'-diphenyl-2,2'-bipyridine) has been prepared and evaluated as an electroluminescent component for light-emitting electrochemical cells (LECs). The complex exhibits two intramolecular face-to-face π-stacking interactions and long-lived LECs have been constructed; the device characteristics are not significantly improved in comparison to analogous LECs with 6-phenyl-2,2'-bipyridine with only one π-stacking interaction.

Title Molecule

The title molecule, C17H15FN4OS2, obtained from 5-fluoro-1-methyl-1H-indol-2,3-dione, and 3-[4-(methylsulfanyl)phenyl]thiosemicarbazide, has an essentially planar conformation (r.m.s deviation for all non-H atoms = 0.116 Å). Intramolecular N—H...N and N—H...O hydrogen bonds generateS(5) andS(6) ring motifs, respectively. In the crystal, C—H...S hydrogen bonds occur between layers of molecules parallel to the (10-1) plane. Face-to-face π–π stacking interactions are also observed.

The combination of these interactions leads to an unusual nearly face-to-face π–π stacking mode. Additional weak C—H...N, C—H...F, N—H...F and P—F...π-ring (tape, py) (with F...centroid distances of 2.925–3.984 Å) interactions are found, leading to a three-dimensional architecture. The RuIIatom is coordinated in a distorted octahedral geometry, particularly manifested by the Namine—Ru—Namineangle of 153.79 (10)°. The counter-charge is provided by two hexafluoridophosphate anions and the asymmetric unit is completed by acetonitrile solvent molecules of crystallization. Disorder was observed for both the hexafluoridophosphate anions as well as the acetonitrile solvate molecules, with occupancies for the major moieties of 0.801 (6) for one of the PF6anions, and a shared occupancy of 0.9215 (17) for the second PF6anion and a partially occupied acetonitrile molecule. A second CH3CN molecule is fully occupied, but 1:1 disordered across a crystallographic inversion center.

In the title mononuclear complex, [HgI2(C12H11NO3)], the HgIIion has a distorted trigonal–planar coordination sphere defined by two I−anions and the N atom of a methyl 2-(quinolin-8-yloxy)acetate ligand. In the crystal, face-to-face π–π stacking interactions, with a centroid–centroid distance of 3.563 (9) Å, are observed.
