    Description / Table of Contents: Solvatochromism of Subgroup VI Metal(0) Complexes with Bidentate Azomethine LigandsSome mononuclear and binuclear chelat compounds of azomethines, derived from the carbonyls of molybdenum and chromium are described. The spectrophotometrical behaviour of the compounds is compared with the behaviour of the diazabutadiene and dipyridyl metalcarbonyls. The complexes show strong negative solvatochromic effects in organic solutions and in polymers.
    Notes: Es werden einige mononukleare und binukleare Chelatkomplexe von Metallcarbonylen der 6. Nebengruppe mit Azomethinen des Pyridincarbaldehyds beschrieben, sowie Phosphin- und Phosphitderivate dieser Chelatkomplexe. Das spektrale Verhalten der Verbindungen wird mit dem ähnlich strukturierter 1,4-Diazabutadien- und Dipyridylkomplexen verglichen. Alle untersuchten Chelatkomplexe zeigen eine starke negative Solvatochromie in organischen Lösungsmitteln und in polymeren Matrizen.

    Description / Table of Contents: The Complexchemical Behaviour of the Phenylglycine-o-Carboxylic Acid and their DerivativesIn solution N-carboxymethyl anthranilic acid (H2A) forms 1,1-complexes (MA) with metal ions. With 2,5-bis(carboxymethylamino) terephthalic acid (H4B) and 2-carboxymethylamino-5-[bis(carboxymethyl)amino]terephthalic acid (H5C), containing in addition to the coordination sphere characteristic for H2A a second one which is separated by space, also protonated and binuclear complexes (MHB-, MH2B, M2B, MHC2-, MH2C- and M2C-) could be detected. From the stability constants of these complexes determined by potentiometric and polarographic methods, a conception on the interaction between two coordination spheres which are separated by space, but coupled by an aromatic electron system, is developed.
    Notes: Phenylglycin-o-carbonsäure H2A bildet mit Metallionen in Lösung 1,1-Komplexe (MA). Bei der 2,5-Bis(carboxymethylamino)-terephthalsäure H4B und der 2-Carboxymethylamino-5-[bis(carboxymethyl)-amino]-terephthalsäure H5C, die neben der für H2A charakteristischen Koordinationssphäre noch eine zweite, räumlich getrennte enthalten, konnten daneben protonierte und binucleare Komplexe (MHB-, MH2B, M2B, MHC2- und M2C-) nachgewiesen werden. Aus den auf potentiometrischem bzw. polarographischem Wege bestimmten Stabilitätskonstanten dieser Komplexe werden Vorstellungen über den Einfluß entwickelt, den zwei voneinander unabhängige, aber durch ein aromatisches Elektronensystem miteinander gekoppelte Koordinationssphären bei der Komplexbildung aufeinander ausüben.

    Description / Table of Contents: Relations between Proton Association and Complex Stability Constants of Substituted Anthranilic AcidsA “model of similar coordination spheres” is developed. From this model a quantitative relation between the proton association constants and the complex stability constants of ligands of the types I and XIV (see text) may be derived. The influence of the substituents X and Y on the Protonation and on the complex formation is reduced to the inductive and mesomeric effect and to the field effect. The complex stability constants calculated with the help of the model are compared with the experimental results.
    Notes: Es wird ein „Modell der ähnlichen Koordinationssphären“ entwickelt, das es ermöglicht, eine quantitative beziehung zwischen den Protonenassoziations- und den Komplexstabilitätskonstanten der Liganden der Typen I und XIV (s. Text) aufzustellen. Der Einfluß der Substituenten X und Y auf die Protonierung und die Komplexbildung wird dabei über den induktiven und mesomeren Effekt sowie über den Feldeffekt erfaßt. Das Modell wird anhand zahlreicher experimenteller Daten überprüft.
