Abstract
The synthesis of a novel 12-crown-4 analogue (cis-p-dioxano-12-crown-4 or cis-3,6,9,13,15-pentaoxabicyclo[9.3.1]pentadecane) is described. T he (1:1) LiNCS complex crystallizes in the monoclinic Cc space group; a = 8.4973(2) Angstrom, b = 18.0659(4) Angstrom, c=8.9168(1) Angstrom, and beta = 90.713(1)degrees with Z = 4. The crown adopts C-1 symmetry to which the Li+ is coordinated in a rectangular pyramid with an apic al -NCS.
