    Syntheses and crystal structures of Ni(II) complexes with pyridine-based macrocyclic ligands

  • Original language description

    Three pyridine-based macrocyclic ligands, two containing one pyridine pendant arm (L-1 and L-2) and one containing piperazine rings in the macrocyclic scaffold (L-3), with an increasing size of the macrocycle from 12-, 14- to 30-membered ring for L-1-L-3 were synthesized and characterized. A series of Ni(II) complexes with all these ligands, with molecular formulas [NiL1(CH3OH)](ClO4)(2) (1), [NiL2(CH3CN)](ClO4)(2) (2), and [Ni2L3(DMF)(2)(CH3CN)(2)](ClO4)(4) (3) (DMF = N,N-dimethylformamide), was prepared and thoroughly characterized. Single crystal X-ray structural analysis confirmed that all the complexes have a coordination number of six and their geometries are close to octahedral. In the case of the mononuclear complexes 1 and 2, all the nitrogen atoms of the macrocycle are coordinated, however, in the dinuclear complex 3 with the piperazine-based ligand L-3, two nitrogen donor atoms (of the total number of ten) are uncoordinated. The first coordination spheres of all the complexes are completed by solvent molecules. The values of effective magnetic moments, determined by the Evans method in solution, are 3.12, 3.19 and 4.36 mu(B) for complexes 1, 2 and 3, respectively, which correspond well to the theoretical spin-only values.
