Abstract
A new centrosymmetric mononuclear nickel(II) complex, [Ni(La)2] (I), and a new mononuclear zinc(II) complex, [Zn(Lb)(N3)(AMP)] (II) (La = 2-iminomethyl-4-methylphenolate, Lb = 4-methyl-2-[(4-methylpyridin-2-ylimino)methyl]phenolate, AMP = 2-amino-4-methylpyridine), have been prepared and characterized by elemental analysis, IR and UV-Vis spectra, and single-cyrstal X-ray diffraction (CIF files CCDC nos. 1059023 (I) and 1059024 (II)). Complex I crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 16.067(2), b = 5.7222(6), c = 7.9004(9) Å, β = 92.471(4)°, V = 725.7(1) Å3, Z = 2, R 1 = 0.0298, and wR 2 = 0.0695. Complex II crystallizes in the triclinic space group \(P\bar 1\) with unit cell dimensions a = 7.649(1), b = 10.414(2), c = 13.903(3) Å, α = 106.896(2)°, β = 91.581(2)°, γ = 103.033(2)°, V = 1027.3(4) Å3, Z = 2, R 1 = 0.0372, and wR 2 = 0.0823. The Ni atom in I is in a square planar coordination, and the Zn atom in II is in a tetrahedral coordination. Crystals of the complexes are stabilized by hydrogen bonds and p···p interactions.
