    Description / Table of Contents: Dimethyl(and -ethyl)-amino-dimethylglyoxime (H2L and H2M, respectively) react with Ni(II) and Pd(II) forming innercomplexes which are analogs of bis-(dimethylglyoximato)-nickel resp. -palladium. The tertiary amino groups have no ligand functions, they are, however, readily protonated to give quarternary ammonium salts such as Ni(H2L)2X2 with X = Cl, ClO4. In connection with the compounds Ni(H2L)2Cl2 and Ni(H2L)2Cl2, 2 H2O, the problem of isomeric Ni(II) complexes of vic-dioximes is discussed.
    Notes: Dimethylamino- und Diäthylamino-dimethylglyoxim (H2L und H2M) bilden mit Nickel(II) und Palladium(II) Innerkomplexe, die Analoga zum Bis-(dimethyl-glyoximato)-nickel bzw.-palladium darstellen. Die tertiären Aminogruppen von H2L und H2M nehmen nicht an der Komplexbildung teil, vermögen aber auch dann, wenn die Dioximliganden an ein Zentralatom gebunden sind, Protonen anzulagern und geben damit den Anlaß zur Bildung quarternärer Ammoniumsalze wie Ni(H2L)2Cl2 und Ni(H2L)2(ClO4)2. Im Zusammenhang mit den Verbindungen Ni(H2L)2Cl2 und Ni(H2L)2, 2 H2O wird das Isomerieproblem bei Nickel(II)-Komplexen vicinaler Dioxime diskutiert.
