Abstract
[NiL(SeCN)2(H2O)] [L=bis(3-aminopropyl)amine (dpt), (1), (2-aminoethyl)(3-aminopropyl)amine (aepn), (2) and bis(2-aminoethyl)methylamine) (medien), (3)] have been synthesized and characterized in the solid state by X-ray single crystal analysis (1 and 2), IR, electronic spectra and magnetic measurement. Structure analyses of (1) and (2) reveal that the nickel(II) center is coordinated in a distorted octahedral fashion and the two SeCN groups are attached in trans position. Upon heating they undergo deaquation followed by color change, yielding dinuclear species bridging through selenocyanate. The deaquated dinuclear complexes have been characterized by IR, electronic spectra and magnetic susceptibility measurement.
