Transition metal complexes of a hydrazone derived from hydralazine hydrochloride and 3,5-di-tert-butylsalicylaldehyde
Mononuclear Co(III), Ni(II) and Cu(II) coordination compounds of ( E )-1-(3,5-di-tert-butyl-2-hydroxybenzylidene)-2-(phthalazin-1-yl)hydrazine ( LH ) were prepared and characterized by physicochemical and spectroscopic methods. The metal-to-ligand ratio was found to be 1:2 in [Co( L ) 2 ]Cl·2H 2 O (...

| Zusammenfassung: | Mononuclear Co(III), Ni(II) and Cu(II) coordination compounds of (
E
)-1-(3,5-di-tert-butyl-2-hydroxybenzylidene)-2-(phthalazin-1-yl)hydrazine (
LH
) were prepared and characterized by physicochemical and spectroscopic methods. The metal-to-ligand ratio was found to be 1:2 in [Co(

)
2
]Cl·2H
2
O (
1
) and [Ni(
L
)
2
]·2H
2
O (
2
), while it is 1:1 in [Cu(
L
)Cl]·2CH
3
OH (
3
). The X-ray crystal structures of
LH
and complex
1
is are reported.
LH
shows monobasic behavior, coordinating through NNO donor atoms. The complexes were investigated for their antimicrobial properties. Complexes
1
and
3
show excellent antibacterial and antifungal activities, respectively. |
