A series of biologically active complexes were prepared using meloxicam (H2mel) and 1,10-phenanthroline monohydrate (Phen) as ligands.The compositions of all complexes were elucidated by infrared, electronic absorption and 1 H NMR spectroscopy, elemental analyses, magnetic moments, conductance and TG-DTG measurements.The analytical and spectroscopic data revealed that H2mel acts as a mono basic bi...
