Ns. Cho et al., 1,5-[5,5 '-(1,3-phenylenedimethylenedithio)bis(2,3-dihydro-2-oxo-1,3,4-thiadiazol-3-yl)]-3-oxapentane, ACT CRYST E, 57, 2001, pp. o368-o369
Two molecules of the title compound, 3,5,15,17-tetrathia-7,13,24,25-tetraaz
atetracyclo[17.3.1.1(4,7).1(13,16)]pentacosa-1(23),4(24),16(25),19,21-penta
ene-6,14-dione, C16H16N4O3S4, having slightly different hollow and curved c
onformations, form the asymmetric unit. Each molecule provides an internal
cavity of cage-like shape to form a host-guest complex.
