Abstract Mono- and diperchlorates of phosphorylated diazacycloalkanes (PDAC),viz. 1,5-bis(2-diphenylphosphorylethyl) -1,5-diazacyclooctanes (1a, 1b), 1,4-bis(2-diphenylphosphorylethyl)- 1,4-piperazine (2a), and 1-methyl-4-(2-diphenylphosphorylethyl)-1,4-piperazines (3a, 3b), were prepared. The formation of inter- and intramolecular hydrogen bonds in PDAC perchlorates and some model compounds in the solid state and in solution was investigated by IR spectroscopy. The dependence between the effect of the hydrogen bond formation and association of the ions in solution was analyzed. Conformational analysis of the cations of PDAC was carried out.
