Teza

X–ray data [1] were obtained for the N,N’–dibenzyl–1,4,10,13–tetraoxo–
7,16–diazoniacyclooctadecane bis(tetrafluoroborate) monohydrate,
(C26H40N2O4)2+.2(BF4)–.H2O, (1) at 123 K. (1) crystallizes in triclinic crystal system,
sp.gr. P–1 (Fig.). The slight distortion of the BF4
– tetrahedron is indicated by the
B–F distances being in the range 1.384(2)–1.399(2) Å and the F–B–F angles
being in the range 108.0(2)–111.0(2)º.
The phenyl groups of the benzyl sidearms are turned above and below
the macrocycle; C–H...π interactions between the phenyl substituents and

two macrocyclic methylene H atoms govern the overall conformation of the
macrocycle. Bridging tetrafluoroborate anions link the macrocyclic cations, via
weak C–H...F hydrogen bonds, into channels running along [100] and filled by
the weakly hydrogen–bonded water molecules.
