Two new zinc(II) acetates with 3– and 4–aminopyridine: syntheses and structural properties
Acta Chimica Slovenica
Dedicated to the memory of Prof. Dr. Jurij V. Bren~i~. 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(CH 3 COO) 2 · 2H 2 O or dissolving solid Zn(CH 3 COO) 2 · 2H 2 O 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
... nthesized by the reaction of Zn(CH 3 COO) 2 · 2H 2 O and 3-aminopyridine (3-apy), are built of trinuclear complex molecules with the formula [Zn 3 (O 2 CCH 3 ) 6 (3apy) 2 (H 2 O) 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(CH 3 COO) 2 · 2H 2 O with 4-aminopyridine (4-apy), consist of a mononuclear complex [Zn(O 2 CCH 3 ) 2 (4-apy) 2 ](2). Hydrogen-bonding interactions in the crystal structures of both complexes are reported.
