The X-ray crystal structure of naphtho-9-crown-3 ether, 1 is reported. The molecule crystallizes in the monoclinic P2(1)/c space group with a = 8.866(2) Å, b = 6.451(1) Å, c = 20.110(4) Å and β = 91.055(4)°, with Z= 4. The 2:1 naphtho-9-crown-3 LiClO4complex, 2 crystallizes in the triclinic P-1 space group with a=10.5075(10) Å, b= 11.7283(11) Å, c = 15.9921(15) Å and β = 84.289(2)°, with Z = 2. There are two distinct complexes found in the crystal, one ordered and one disordered in the crown portion of the molecule.13C CPMAS NMR spectra for 1 and 2 are presented. © 2002 Elsevier Science B.V.
