Abstract
The reactions of (5,7-dimethyl-1,4,8,11-tetraazacyclotetradeca-4,6-dienato)nickel(II) iodide with benzoyl chloride and isophthaloyl dichloride gave mononuclear 1 and dinuclear 2 nickel(II) complexes, respectively. Complex 1 crystallized in space group P21/a with Z = 4, a = 23.704(10), b = 7.726(3), c = 11.581(4) A, β = 104.16(3)°, V = 2056.5(1.4) A3. The benzoyl group is positioned at the 6 position of the macrocycle and tilted to the NiN4 plane by 67.9° due to the steric hindrance from two methyl groups. Complex 2 crystallized in space group with Z = 2, a = 12.124(3), b = 16.484(4), c = 10.243(4) A, α = 94.84(3), β = 111.04(3), γ = 80.69(2)°, V = 1884.6(1.1) A3. The metal ions are 12.777(6) A apart, and the two coordination planes are nearly co-planar, the dihedral angle between them being 164.4°.
