Abstract
The reaction of N,N'-bis(2-hydroxyacetophenone)-l,2-propanediamine (a,a'-Me Salpd) with transition metal cations including CuⅡ or NiⅡ in methanol results in two complexes [Cu(a,a'-Me-Salpd)] 1 and [Ni(a,a'-Me-Salpd)] 2. Their crystal structures were determined by X-ray diffraction analysis. Crystal data for 1: monoclinic, space group P21/n, a = 12.3752(6), b =10.5061(5), c = 26.5617(2) (A), β = 103.342(1)°, C38H40N4O4Cu2, Mr= 743.82, Z = 4, V = 3360.2(3) (A)3, Dc= 1.470 g/cm3,μ = 1.313 mm-1, F(000) = 1544, R = 0.0681 and wR = 0.1555 for 4523 observed reflections (I ＞ 2σ(I)); and those for 2: monoclinic, space group P21/n, a = 10.4207(2), b=12.4627(2), c = 25.7322(1) A, β = 99.909(1)°, C38H4oN4O4Ni2, Mr= 734.16, Z = 4, V = 3291.99(8) (A)3, De = 1.481 g/cm3,μ = 1.192 mm-1, F(000) = 1536, R = 0.0766 and wR = 0.1873 for 3433 observed reflections (I ＞ 2σ(I)).
