Self-assembly of Schiff base ligands 2,4-dibromo-6-[(3-dimethy laminopropylimino)methyl]phenol (BMP) and 2-[(3-cyclohexyl aminopropylimino) methyl]-6-methoxyphenol (CMP) with nickel (II) acetate and ammonium thiocyanate forms two centrosymmetric mononuclear nickel(II) complexes, [Ni(BMP)2] (1) and [Ni(CMP)2(NCS)2] (2), respectively. Complex 1 crystallizes in a monoclinic space group C2/c, while complex 2 crystallizes in a hexagonal space group R-3. Both crystal structures were characterized by X-ray diffraction analyses and IR spectra. Each NiII center in the complexes has NiN4O2 coordination environment, with the two imine N and two phenolate O atoms located in the base plane. The difference between the two coordinations is the axial donors, viz. amino N atoms for 1, and thiocyanate N atoms for 2. Copyright Taylor & Francis Group, LLC.
