Monotype ligand coordination compounds of zinc nitrate with benzamide and urea were synthesized. The synthesis is carried out by mechanochemical (solid-phase) method, which does not require the use of scarce solvents as in the synthesis stage, so and cases when highlighting the main product and allows for a short time to synthesize complexes of various compositions. The composition and individuality of the synthesized compounds were established by elemental analysis. Using vibrational spectroscopy method resulting for coordinating organic ligand have been proven, water molecules surroundings of the central ion of the complex compounds. Based on the data of IR spectroscopy, it was found that the molecules of benzamide and urea coordinated with the central atom through an oxygen atoms, and anions of nitric acid are coordinated by two oxygen atoms of the nitro group – bidentantly
