The manganese(III) complex with chelating Schiff base ligand: X-ray structure, spectroscopic and computational studies

A new Mn(III) complex, [MnCl(H(2)O)(L)].H(2)O.C(2)H(5)OH, where L=2,2'-[1,2-phenylenebis[nitrilomethylylidene]]bis(6-methoxyphenolate), has been synthesized and characterized by single-crystal X-ray diffraction. There is a good agreement between calculated and experimental structural data. The complex is crystallized in orthorhombic with space group Pbca. The Mn1 atom is coordinated with one Schiff base ligand, one water molecule and one chloride anion, forming a six-coordination number. The electronic and fluorescence spectra of the complex were also studied.

(S)-2-(1-Hydroxyethyl)benzimidazolium dihydrogen phosphate

The asymmetric unit of the title compound, C₉H₁₁N₂O⁺·H₂PO₄⁻, is built up from a 2-(1-hydroxy­ethyl)benz­imid­a­zol­ium cation and a dihydrogen phosphate anion which are connected by an N—H⋯O hydrogen bond. The cation is roughly planar, the dihedral angle between the rings being only 1.4 (2)°. The S configuration is deduced from the synthetic pathway and supported by the refinement of the Flack parameter. Inter­molecular O—H⋯O and N—H⋯O hydrogen bonds build up a three-dimensionnal network.

Aggregation-induced and crystallization-enhanced emissions of 1,2-diphenyl-3,4-bis(diphenylmethylene)-1-cyclobutene

1,2-Diphenyl-3,4-bis(diphenylmethylene)-1-cyclobutene can be induced to emit efficiently by aggregate formation, with the crystalline aggregates emitting brighter, bluer lights than their amorphous counterparts.
