Four new NiII, CoII, ZnII, and CuII complexes with the promising anti-tuberculosis drug (E/Z)-N′-((5-Hydroxy-3,4-bis(hydroxymethyl)-6-methylpyridin-2-yl)methylene)-isonicotino-hydrazide (LH) were synthesized characterized by structural methods: single-crystal X-ray diffraction, vibrational spectroscopy, mass spectrometry. The ZnII metal ions form only amorphous phases various morphologies accor...
