The X-ray crystallographic analysis of benzoaza-12-crown-4 hydrochloride crystals is performed for the first time: space group P1, a = 7.7497(4) Å, b = 9.2224(5) Å, c = 10.2395(5) Å, α = 99.3965(10)°, β = 101.8387(11)°, γ = 112.6470(10)°, V = 636,81(6) Å3, Z = 2, ρcalc = 1.355 g/cm3. The conformation of the 12-membered ring of the molecule is determined. © 2015 Pleiades Publishing, Ltd.

A number of new stable azomethine crown ether derivatives have been synthesized by condensation of 4-aminobenzo-15-crown-5 with aromatic aldehydes. Complexation of the products with transition metal cations (Cu2+, Zn2+, Fe3+, Co3+, Ni3+) has been studied by spectrophotometry. © 2015 Pleiades Publishing, Ltd.
