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

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.
