Abstract: | The title compound (C13H30N2O7S) has been determined from three‐dimensional X‐ray diffraction data. The crystals are monoclinic, a = 22.654(8) Å, b = 8.652(4) Å, c = 23.925(9) Å, β = 123.880(9)°, V = 3893(3) Å3, Z = 8, Dcalc = 1.192 g/cm3, space group C2/c. The structure was solved by direct methods and refined by full‐matrix least squares method (R = 0.051). The ammonium cation is displaced by 1.08 Å from the mean plane of the ligand causing hydrogen bonding with the macrocyclic O atoms in a perching arrangement. The thiocyanate anion forms an extended hydrogen bonded chain with the cation via the occluded water molecule. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
