Laterally non-symmetric aza cryptand molecules stitched by water

Abstract

Crystal structure of the compound L·4H2O (L = aza cryptand) and its supramolecular assembly via H-bonding through water molecules are described here. The compound crystallizes in the cubic space group Pa3 (no. 205) with the following lattice parameters: a=b=c=19.023(2) Å, V=6883.9(4) Å3, Z=8, R 1=0.0592, wR 2 = 0.1572, S=0.964.
