X-ray structure and vibrational spectroscopy of a cobalt(II) complex prepared with excess of 4-hydroxybenzhydrazide

The X-ray structures, vibrational spectroscopy and antimicrobial activity of nickel(II) complexes with 4-hydroxybenzhydrazide

“…The bond lengths and angles in three 4hbah ligands (Table 2) are similar to those reported for the 4-hydroxybenzhydrazide complexes with copper(II) [21] and cobalt(II) ions [22,23]. However, there are two subtle structural differences between these ligands.…”
