A series of boroncomplexes of tridentate acyl pyridylhydrazones were prepared. Their facile synthesis relies on arylboronic acids for boron incorporation, enabling significant structural diversity, dual-state emission, and reversible electrochemical reductions. Donor-acceptor architectures, constructed by leveraging triphenylamine and carbazole-functionalized arylboronic acids, result in aggregation-induced

The ligand 2-hydroxy-benzoic acid (phenyl-pyridin-2-yl-methylene)-hydrazide (Hbpph) and its Mn(II), Ni(II), Cu(II) and Zn(II) complexes have been synthesized. The metal complexes are characterized by elemental analyses, molar conductance, magnetic susceptibility measurements, electronic, IR and NMR spectral techniques. The molecular structures of the ligand and metal complexes have been determined by single crystal X-ray diffraction studies. Hbpph acts as monobasic tridentate ligand and coordinates through pyridyl-N, azomethine-N and enolate-O with metal ion. Magnetic moments and electronic spectral studies of Mn(II), Ni(II) and Cu(II) complexes suggest a high spin six coordinate geometry around metal ion. Single crystal structure of the ligand molecule displays a Z molecular conformation about the >C=N- bond, whereas, the metal complexes exhibit E-configuration. The molecular structures of the metal complexes are stabilized by various H-bonding and C-H...pi interactions. (C) 2014 Elsevier Ltd. All rights reserved.
