ChemInform Abstract: COMPLEXES OF METAL DITHIONATE WITH BENZOYLHYDRAZINE

Abstract

Die 1:3‐molare Umsetzung entsprechender Metall(II)‐dithionate mit dem Titelliganden in wäßriger Lösung führt zu den oktaedrischen, kationischen Komplexen (I), die als Monohydrat isoliert werden, und zu dem neutralen, tetragonal‐bipyramidalen Cu(II)‐Komplex (II), in dem vermutlich das axial‐O‐gebundene Dithionat eine Brücke zu einem weiteren Komplexmolekül bildet.

Polymeric and mixed ligand complex of cobalt(II) and 4-hydroxybenzhydrazide: Crystal structure and vibrational spectroscopy

“…The research has been mainly focused on the copper(II) [6][7][8][9][10][11][12][13][14] and nickel(II) [6,7,11,14] complexes. Only two communications have taken into account the 4hbah complexes with dithionate cobalt salts [7,14].…”

“…The research has been mainly focused on the copper(II) [6][7][8][9][10][11][12][13][14] and nickel(II) [6,7,11,14] complexes. Only two communications have taken into account the 4hbah complexes with dithionate cobalt salts [7,14]. Based on the infrared spectroscopic measurements, the authors have proposed the general formula of the complexes (MeL n S 2 O 6 ÁmH 2 O where n = 2, 3; m = 0, 1, 2; L -various benzhydrazides) and coordination mode through the N-amino and O-carbonyl atoms without any deeper consideration of the cobalt coordination environment, which frequently is completed by the solvent molecules.…”

The X-ray revision of the structure of bis(4-hydroxybenzhydrazide)copper(II) sulfate(VI) dihydrate and its vibrational spectroscopy

“…In already published articles [6][7][8], some chelate complexes with different d-electron metal ions were reported. Their structures were mostly proposed on the basis of elemental analyses, pH-metrical, and selected spectroscopic studies.…”
