The 2-methoxy-pyrido[1,2-a]quinoxalin-11-ylium bromide (2MPQYB) crystal was characterized from single crystal X-ray diffraction (SCXRD) and spectroscopy analysis. The fluorescence spectrum of the compound showed one broad peak at 473 nm. The supramolecular arrangement in solid state was confirmed by 2D-fingerprint plots and Hirshfeld surface analysis. An additional topological analysis from quantum theory of atoms in molecules (QTAIM) highlights the observed halogen bonds on solid state for 2MPQYB. Also the supermolecule (SM) approach was used to simulate the crystalline environment with 246,064 atoms and an ab-initio calculation method, which includes the Density Functional Theory (DFT) at CAM-B3LYP/6–311++G(d,p) level, was used to estimate the crystal linear refractive index and the third-order nonlinear susceptibility at the frequency of ω=0.086a.u. (λ = 532 nm) and the obtained values were 1.85 and χ3=621.14×10?22m2/V2 respectively. This χ3-value is up to 312.13 times greater than obtained for others organic crystals of the literature, thus indicating that the 2MPQYB can be considered for various applications of NLO materials.

We report the preparation, crystal structure, electrochemistry, and emission properties of Ir(CC:)3, where CC: is an N-heterocyclic carbene ligand. Two synthetic approaches are introduced for generating Ir(iii) complexes bearing imidazolium-bas
N,N-Chelate nickel(II) complexes bearing Schiff base ligands as efficient hydrogenation catalysts for amine synthesis

Five N, N-chelate nickel (II) complexes bearing N-(2-pyridinylmethylene)-benzylamine ligands with different substituent groups were synthesized in good yields. The nickel complexes exhibited prominent catalytic efficiency toward amine synthesis from nitro compounds by using NaBH4 or H2 as hydrogen source through two catalytic systems. Various amines with different substituents were obtained in moderate to excellent yields. All substrates with electron-donating and electron-withdrawing properties were tolerated in the two reduction systems. Given the efficient catalytic activity, broad substance scope, and mild reduction conditions, the nickel catalysts have potential applications in industrial production.

Herein, we broaden the application scope of (cyclo-pentadienone)iron complexes 1 in C=N bond reduction. The catalytic scope of pre-catalyst 1b, which is more active than the “Kn?lker complex” (1a) and other members of its family, has been expanded to the catalytic transfer hydrogenation (CTH) of a wider range of aldimines and ketimines, either pre-isolated or generated in situ. The kinetics of 1b-promoted CTH of ketimine S1 were assessed, showing a pseudo-first order profile, with TOF = 6.07 h–1 at 50 % conversion. Moreover, the chiral complex 1c and its analog 1d were employed in the enantioselective reduction of ketimines and reductive amination of ketones, giving fair to good yields and moderate enantioselectivity.
