Background. Modern science of Uzbekistan has a tendency to establish a close cooperation with real sectors of the economy. Such cooperation is particularly important for agriculture. Nowadays when because of an ecological situation and climatechanges productivity of agricultural plants is gradually decreased it is essential to suggest new fertilizers and growth stimulators. Our group is conducting asystematic research in order to elaborate stimulators on the base of metal complexes. We are using well known auxin 2,4-dichlorophenoxyacetate (2,4-D) for preparation of the new coordination compounds. Purpose.The purpose of the current investigation is to obtain metal complex containing 2,4-D and also effective plant growth agent MEA with further determination the structure of the synthesized compound. Methodology.X-ray crystallography at room temperature using anXcalibur R Oxford Diffraction automated diffractometer was main structure determination method. Originality.The supramolecular complex has been obtained and its crystal structure and molecular characteristics have been determined for the first time. Findings.A novel supramolecular compound with a participation of the 2,4-dichlorophenoxyacetate (2,4-D) complex molecule [Ni(2,4-D)2(H2O)4], free 2,4-D ligand, monoethanolamine (MEA) and crystallization water molecules has been synthesized. The structure of the synthesized complex is determined by the single-crystal X-ray diffraction method as {2[Ni(2,4-D) 2(H2O)4]·(MEA)·2(2,4-D)·4H2O}. The crystal structure of the supramolecular complex {2[Ni(2,4-D)2(H2O)4]·(MEA)·2(2,4-D)·3H2O} is complicated. Besides coordination to metal atom two 2,4-D ligand molecules occupy outer coordination sphere. One MEA molecule is displaced from inner sphere despite of its high chelating capability. In order to associate these three components by H-bonds 4 water molecules participatein the crystal structure. In result of complicatedsystem of intermolecular H-bons 3-D supramolecular network is formed. Highlights: - The novel compound has been prepared in the form ofsupramolecular complex consisting of four components.
