| Abstract: The complexes of Ni(NCS)2, Ni(NO3)2 with l,7,10,16-tetraoxa-4, 13-diazacyclooctadecane have been prepared and characterized by elemental analyses, IR, DTA-TG, electrical conductance, visible and near infrared solid reflectance spectrum as well as magnetic moments. The absorption bands of d-d electrons transition are assigned, values of Dq and B are calculated. The complex Ni(NCS)2C12H26O4N2 forms single crystal with the foliowing crystallographic parameters, monoclinic, P21/a,a = 7.512(l)Å, b = 8.524(1)Å, c=15.286(3)Å; β= 100.29(1)Å,V= 963.05Å3, Z = 2. The structure was solved by Patterson method and refined by least square technique to a discrepancy factor of R = 0.027. It is shown that Ni(Ⅱ) ion is coordinated to two nitrogen atoms of thiocyanates and two oxygen atoms and two nitrogen atoms of macrocyclic ligand forming a distorted octahedron. |
