Abstract

The reaction of poorly soluble manganese(II) bis(1-hydroxyethylidene)diphosphonate tetrahydrate (Mn(H₃L)₂•4H₂O) with 2-aminoethanol (H₂NCH₂CH₂OH) in an aqueous medium on heating to 70—80 оС causes the initial formation of soluble manganese(II) bis(1-hydroxyethylidene)diphosphonate tris(1-hydroxyethaneaminium) (Mn(H₃L)2• •3H₂NCH₂CH₂OH•4H₂O), which then disproportionates to slightly soluble manganese(II) (1-hydroxyethylidene)diphosphonate-2-hydroxyethaneaminium (MnH₂L•H₂NCH₂CH₂OH) and coordination polymer of 1-hydroxyethylidenediphosphonic acid with 2-aminoethanol containing no metal cations. In the course of the reaction, MnH₂L•H₂NCH₂CH₂OH precipitates as whiskers that are grouped into a leaf (lepidoid) structure. The latter was examined by IR spectroscopy, X-ray phase analysis, scanning electron microscopy, atomic force microscopy, optical microscopy, and thermal desorption of nitrogen. The starting and resulting manganese compounds refer to poorly soluble crystalline complexes. The presence of a 2-aminoethanol molecule in the final product leads to an increase in the solubility from 0.40 to 0.54 g in 100 mL of the solution. Poorly soluble MnH₂L•H₂NCH₂CH₂OH is easily converted to a soluble form by the treatment with 2-aminoethanol or 2-amino-2-(hydroxy- methyl)propane-1,3-diol (H₂NC(CH₂OH)3). The agronomical efficiency of a solution of the Mn(H₃L)₂•3H₂NCH₂CH₂OH•4H₂O complex was studied on the cultures of white lupine Degas, spring wheat Ester, spring rape, and pea Stabil.
