College, Gyanpur, Sat Ravida Nagar, 221304 (INDIA) <p style="text-align: justify;">Bis-chelates with Pd(II) and Pt(II) and Tris-chelates with Ru(III), Rh(III) and Ir(III) with anti-tubercular isonicotinic acid hydrazide drug have been isolated and characterized on the basis of micro analytical, Magnetic Moment, electronic and IR spectral data. The deprotonation of enol tautomeric form of -OH group occurs at pH=8 and the ligand acts as bidentate (N O donor). Metal-ligand vibrations in far IR spectra have also been located and tentatively assigned.</p> https://ultraphysicalsciences.org/paper/1131/ Metal Chelates anti-Tubercular Isonicotinic Acid hydrazide
