The preparations of the nickel-morpholine (Morph) complexes Ni(NO2)2·3Morph and Ni(ClO4)2·4Morph·2H2O are described. The thermal treatment of this perchlorate and of NiSO4·2Morph led to the isolation of Ni(ClO4)2·2Morph·2H2O and NiSO4·Morph. The magnetic moments, diffuse reflectance spectra and infrared spectra of these compounds are all compatible with a pseudo-octahedral environment around the nickel atom.

Die Darstellung der Nickel-Morpholin(Morph)-Komplexe Ni(NO2)2·3Morph und Ni(ClO4)2·4Morph·2H2O wird beschrieben. Die thermische Behandlung dieses Perchlorates und von NiSO4·2Morph ergibt Ni(ClO4)2·2Morph·2H2O und NiSO4Morph. Magnetisches Moment sowie diffuse Reflektionsspektren und Infrarotspektren dieser Verbindungen sind kompatibel mit einer pseudooktaedrischen Koordination des Nickelatoms.


Описано получение ад дуктов нитрита, сульф ата и перхлората никеля с морфолином (Морф) следующего сост ава: Ni(NO2)2·ЗМорф, NiSO4·2Морф и Ni(ClO4)2·4Морф·2H2O. Термическая обработ ка двух последних сое динений привела к выделению с оединений NiSO4·Морф и Ni(ClO4)2·2Морф·2H2O. Ма гнитные моменты, спектры диффузного о тражения и ИК спектры показали, что эти соединения об ладают псевдооктаэдрическ ой структурой.
