2-Hydroxyacetophenone nicotinic acid hydrazone (H 2 ApNH) was synthesized as a part of our work, in search for non-linear optical crystal based on hydrazones, and studied spectroscopically. Complete NMR assignments for the hydrazone was made using COSY homonuclear and HMQC heteronuclear correlation techniques. Solid state reflectance was also studied in order to understand the electronic structure...
An interesting series of eight neutral ternary Co(III) complexes of 2-hydroxyacetophenone N(4)-substituted thiosemicarbazones (H 2 L), bidentate heterocyclic bases 2,2'-bipyridine (bipy)/1,10-phenanthroline (phen) and azide with a general formula [MLB(N 3 )] were prepared. The complexes were characterized by means of spectroscopic methods. The coordination geometry around Co(III) in...
