The structure of 4 was unequivocally solved by single-crystal X-ray-diffraction analysis. The compound crystallizes in a monoclinic cell (space group P 2(1/c)). with two molecules in the asymmetric unit. held together by intermolecular H-bonds. Compound 4 could be interesting as a bi- or even tridentate ligand, and exhibits a strong fluorescence upon excitation at 310 nm. A mechanism, based on the observed C-N bond cleavage, is proposed.eninfo:eu-repo/semantics/closedAccess[No Keyword]Article90612111217WOS:0002476906000162-s2.0-3444732728410.1002/hlca.200790120Q3Q2
