Determination of cobalt (II) with o- (2-thiazolylazo) phenol derivatives

Extractive Spectrophotometric Determination of Iron (ii) with [n - (o -methoxy Benzaldehyde)- 2 - Amino Phenol]

A simple, rapid and sensitive spectrophotometric method has been developed for the determination of Fe (II) by using N (o methoxy benzaldehyde) 2 aminophenol (NOMBAP) as an analytical reagent. NOMBAP has been synthesized and characterized by elemental and spectral analysis. NOMBAP extracts Fe (II) quantitatively (99.67%) into ethyl acetate from an aqueous solution of pH range 5.6 6.8. The ethyl...

Diaqua­bis(4-bromo-2-formyl­phenolato-κ2 O,O′)cobalt(II)

In the title complex, [Co(C(7)H(4)BrO(2))(2)(H(2)O)(2)], the Co(II) ion, which lies on a crystallographic inversion center, is coordin-ated by four O atoms from two bidentate 4-bromo-2-formyl-phenolate ligands and two O atoms from two water ligands in a slightly distorted octa-hedral environment. In the crystal structure, one-dimensional chains are formed through inter-molecular O-H⋯O hydrogen ...

Azido­{2-[bis­(2-hy­droxy­eth­yl)amino]­ethano­lato-κ4 N,O,O′,O′′}cobalt(II)

In the title complex, [Co(C(6)H(14)NO(3))(N(3))] or [Co(teaH(2))N(3)], the Co(II) atom resides in a trigonal-bipymidal O(3)N(2) environment formed by three O atoms and one N atom from a simply deprotonated tetra-dentate triethano-lamine ligand, and one N atom from an azide ligand. The O atoms define the equatorial plane whereas both N atoms are in axial positions. The mononuclear units are link...
