    Description / Table of Contents: Diacetyl monoxime-β-pyridyl-(2)-ethylimine (DPE) reacts with Ni(II) salts forming paramagnetic complexes of the type Ni(DPE)2X2 (with X = NO3, ClO4, J-). DPE behaves as a tridentate ligand. In the compounds Ni(DPE)2(SCN)2 and Ni(DPE)(SCN)2, the thiocyanate ions participate, at least partially, in the complex formation.Whereas Cu(II) ions normally form 1,1 complexes of the type Cu(DPE)Y2 with Y = Cl-, Br-, NO3, from the interaction between the perchlorate and DPE a chelate compound of the formula [Cu(DPE - H)]ClO4, probably being dimeric, results. The compounds Zn(DPE)Cl2 and Zn(DPE)J2 are non-electrolytes in acetonitrile.
    Notes: Diacetylmonoxim-β-pyridyl-(2)-äthylimin (DPÄ) bildet mit Nickel(II)salzen paramagnetische Komplexe des Typs Ni(DPÄ)2X2 (X = NO3. ClO4- und J-). DPÄ fungiert darin als dreizähliger Ligand. In den Verbindungen Ni(DPÄ)2(SCN)2 und Ni(DPÄ)(SCN)2 sind die Rhodanidionen zumindest teilweise an der Komplexbildung beteiligt. Kupfer(II)-Ionen bilden mit DPÄ die 1,1-Komplexe Cu(DPÄ)Y2 [Y = Cl-, Br- und NO3]. Nur bei der Umsetzung mit Kupferperchlorat entsteht ein, wahrscheinlich dimerer, Innerkomplex [Cu(DPÄ - H)]ClO4. Die Verbindungen Zn(DPÄ)Cl2 und Zn(DPÄ)J2 besitzen in Acetonitril Nichtelektrolytcharakter.
