title: Two new zinc(II) acetates with 3- and 4-aminopyridine: syntheses and structural properties.
abstract: The synthesis and characterization of two new zinc(II) coordination compounds with 3- and 4-aminopyridine are reported. They were obtained after adding a water solution of Zn(CH3COO)2·2H2O or dissolving solid Zn(CH3COO)2 ∙ 2H2O in methanol solutions of 3- and 4-aminopyridine. The products were characterized structurally by single-crystal X-ray diffraction analysis. Colourless crystals of the compound synthesized by the reaction of Zn(CH3COO)2·2H2O and 3-aminopyridine (3-apy), are built of trinuclear complex molecules with the formula [Zn3(O2CCH3)6(3-apy)2(H2O)2] (1). The molecules consists of two terminal Zn atoms, coordinated tetrahedrally, and one central Zn atom, coordinated octahedrally. Colourless crystals, obtained by the reaction of Zn(CH3COO)2·2H2O with 4-aminopyridine (4-apy), consist of a mononuclear complex [Zn(O2CCH3)2(4-apy)2] (2). Hydrogen‒bonding interactions in the crystal structures of both complexes are reported.
