A cyclization of azapodand haloderivatives into nitrobenzoazacrown ethers under treatment with various bases and in their absence was investigated. The nitrobenzoazacrown ethers obtained and their complexes with metal cations were studied by X-ray diffraction method and by H-1 NMR titration. In nitrobenzoaza-15-crown-5 a capability to complex Ca2+ cation was found that significantly exceeded similar ability of nitrobenzocrown ether with the same size of the macroring.
