title: The tert-butylammonium perchlorate complex of 2,3-naphtho-18-crown-6 at 115 K.
abstract: In the title complex, tert-butylammonium perchlorate-2,5,8,11,14,17-hexaoxatricyclo[16.8.0.0(20,25]hexac osa- 1(26),18,20(25),21,23-pentaene-ethyl acetate-dichloromethane (4/4/1/1), C4H12N+.C20H26O6.ClO4-.0.25C4-H8O2.0.25CH2Cl2 , the tert-butylammonium cation binds to the macrocyclic host (Chemical Abstracts name: 2,3,5,6,8,9,11,12,14,15-decahydro-1,4,7,10,13,16-hexaoxanaphtho [2,3- b]cyclooctadecin) in the expected tripod arrangement, while the perchlorate anion links naphthyl groups in the crystal through C-H...O-Cl-O...H-C interactions. Thermal motion analysis indicates that the tert-butylammonium group and the perchlorate anion each librate with respect to the host, with amplitudes of 6.2 (4) and 11.4 (2) degrees, respectively.
