“…A sharp band at 1595 cm -1 diagnostic of >C=N-N=C< group (Sayeed, 1971) indicating transformation of the carbonyl group to its enolic form through ketoenol tautomerism and subsequent coordination of the enolic oxygen to metal after deprotonation. Again the appearance of a new band at 1525 cm -1 was characteristic of ν (NCO -) vibration, which further supported the enolic oxygen coordination (Narang, 2000). A weak band around 875 cm -1 due to the rocking mode of vibration, ρ(H 2 O), suggests (Nakamoto, 1997) the presence of coordinated water molecule in the complex, which was also shown by dehydration study.…”

“…The ν(N-N) vibration in the complex shifted to higher frequency (~ 35 cm -1 ), shows coordination through one of the nitrogen atoms of the hydrazide moiety. This shifting of ν(N-N) vibration to higher frequency in Co-complex was attributed to the electron attracting inductive effect when forming the conjugate system (Narang, 2000). (Lever, 1984).…”

“…The ligand content in the synthesized complex was estimated by calibration curve method (Narang, 2000). In this method, a weighed quantity of the complex was dissolved in 10 ml of 6 N HCl and titrated against a standard solution (~0.1N) of KBrO 3 using methyl orange as indicator.…”

Cobalt Complex of type [Co(Hsbh) 2 (NO 3 )(H 2 O)]. 3H 2 O was synthesized and characterized by different analytical procedures, molar conductance, infrared and electronic spectral studies. The complex was found to be 1:2 metal ligand ratio. Molar conductance measurement shows non electrolyte nature of complex. Dehydration studies indicate the presence of coordinated as well as lattice water molecules. Infrared spectral studies indicate that ligand undergo keto enol tautomerism and bond to the metal ion via enolic oxygen and NH 2 group. The electronic spectrum shows octahedral geometry around central cobalt (III) atom.

Mixed-ligand complexes of the types [Ni(Etdtcn)(BH)], [Ni(Budtcn) (BeBH)], and [M(Rdtcn)(salBH)], where M ¼ Co(II), Ni(II), or Cu(II); R ¼ methyl (Me), ethyl (Et), propyl (Prop) or butyl of the dithiocarbonate (Bu); dtcn ¼ dithiocarbonate group; BH ¼ benzoyl-hydrazine anion, BeBH ¼ benzaldehyde benzoylhydrazone anion, and salBH ¼ salicylaldehyde benzoylhydrazone anion have been synthesised. Elemental analyses, molar conductivities, and spectral (IR, UV, and mass) studies have been used to elucidate the structure of the metal complexes. HBH and HBeBH coordinate in the enol form as bidentate ligands forming a square-planar structure around Ni(II). Moreover, the HsalBH ligand 743 ORDER REPRINTS behaves as tridentate anion with all metal ions and an octahedral structure for these complexes is proposed. The three ligands and some of their complexes were screened against three species of bacteria, namely B. cereus (G þve), P. aeruginosa (G 2ve), and S. aureus (G þve) and five types of fungi, A. flavus, A. fumigatus var. albus, A. niger, F. oxysporum or C. tropicum. The HsalBH ligand has shown high activity against bacteria and fungi, probably due to the presence of a hydroxyl group in this ligand.
