CONTRIBUTION TO CO(III) NITROCOMPLEXES CHEMISTRY. NEW ANALAGUES OF NH<sub>4</sub>[CO(NO<sub>2</sub>)<sub>4</sub>(NH<sub>3</sub>)<sub>2</sub>] COMPLEX WITH HEXAMETHYLENETETRAMINE
Abstract:
<p align="justify"> The work presents experimental data about new analogs of ammonium tetranitro-diamine Co (III) complex (Erdmann complex) with hexamethylenetetramine (hta). The base complex obtained, NH<sub>4</sub>[CO(NO<sub>2</sub>)<sub>4</sub>(hta)]<sub>2</sub>, as well as the Erdmann complex, present practical importance for agriculture. They contain nitrogen under cationic, anionic, and molecular form and Co (III) as a micronutrient and serve as a source of other micronutrients through replacement of NH4+ with other complex cations. Some of these complexes are soluble in water, others are hardly soluble and nonhygroscopic. Their efficiency in fertilizing was demonstrated by us experimentally. </p>
