    Description / Table of Contents: Komplexe des Dioxo[4-(2-pyridylazo)resorcinolo]vanadat(V) und charakteristische Infrarot-Banden für die Koordination von PARÜber die Synthese und Eigenschaften der Komplexe des Dioxo [4-(2-pyridylazo)resorcinolo]vanadat(V) wird berichtet. Verglichen mit den Verbindungen von Natrium, Kupfer, Kobalt und Niobium mit 4-(2-pyridylazo)resorcinol zeigen die Infrarot-Spektren der Vanadat-Komplexe sowohl Baden, die für die Koordination des Liganden als auch solche, die für die VO2-Gruppe charakteristisch sind.
    Notes: Synthesis and properties of dioxo [4-(2-pyridylazo)-resorcinolo] vanadate(V) complexes are reported. By comparison with sodium, copper, cobalt, and niobium compounds of 4-(2-pyridylazo)resorcinol infrared spectra reveal characteristic bands for coordinated ligand and VO2 group, respectively.

    Description / Table of Contents: Komplexchemie von Niob und Tantal. XVIII. Peroxo-EDTA Niobate(V) und Tantalate(V)Darstellung und Eigenschaften von Peroxo-Ethylendiamintetraacetatoniobat(V) und -tantalat(V) werden beschrieben. Diese stabilen und kristallinen Komplexe kann man aus Wasser und Wasserstoffperoxid rekristallisieren. Die chemischen und spektralen Untersuchungen stimmen mit der Formel M3I[MV (O2)3EDTA] nH2O2, MI = K, NH4; MV = Nb, Ta; m ≤ 1, überein. Niob und Tantal Verbindungen sind isomorph.
    Notes: Preparation and Properties of peroxoethylenediaminetetraacetato niobates(V) and tantalates(V) are reported. These stable, crystalline complexes can be recrystallized from aqueous and hydrogen peroxide solutions. According to chemical and spectral evidence the complexes correspond to the formula M3I[MV (O2)3EDTA] nH2O2, MI = K, NH4; MV = Nb, Ta; n ≤ 1. Niobium and tantalum compounds are isomorphous.
