The properties of complex compounds produced by template condensation of salicylideneaminoguanidines with salicylaldehyde on a nickel(II) ion matrix are studied. It is shown that the potassium ion in a nitrogen-substituted triazacyclic complex can be replaced by a tetrabutylammonium cation. The electronic structure of the compounds obtained is characterized using UV, IR, and (1H, 13C) NMR spectroscopies. A chelate compound produced from nitroaminoguanidine was found to exhibit the effect of electron density redistribution involving nickel AO. As a result, two benzene rings of the complex anion become nonequivalent. |
