The complex crystallizes in the orthorombic space group Pbca with Z = 8. Lattice parameters are a = 11.451(2), b = 12.842(3), c = 31.330(7) angstrom. The structure was refined to R factor of 0.0547. The Na ion is heptacoordinated. The Na-O-ether distances range from 2.363(4) to 2.433(4) degrees and average 2.404(5) degrees. Perchlorate anion is bounded to sodium ion asymmetrically; the Na-O8 and Na-O9 distances are 2.444(5) degrees and 2.607(5) degrees. The C-O and C-C distances of the 15-membered ring average 1.419(9) and 1.478(12) degrees while the O-C-C and C-O-C angles average 108.2(6)degrees and 115.4(6)degrees.eninfo:eu-repo/semantics/closedAccessChiral Crown EtherSodium Complex15-Crown-5Crystal StructureArticle3812943947WOS:0002599611000102-s2.0-5854908829710.1007/s10870-008-9417-8Q3Q4
