In the title hydrated salt, C36H66N8O6+·6ClO4 -·1.5H2O, the asymmetric unit consists of a hexaprotonated [H6 L]6+ cation, five perchlorate anions in general positions, two on twofold rotation axes (one of which is disordered), and two water molecules of crystallization in general positions, one of them disordered around a twofold crystallographic axis. In the [H6 L]6+ cation, two strong intramolecular N-H⋯N hydrogen bonds occur, involving the N atoms of the oxadiazole ring as acceptors and the closest NH+ groups of each dipropylenetriamine unit. In the crystal, the [H6 L]6+ cations form channels along the a-axis direction, in which the perchlorate counter-ions and the water molecules are lodged. The crystal packing features a network of N-H⋯O and O-H⋯O hydrogen bonds involving the NH+ groups of the [H6 L]6+ cation, the perchlorate anions and the water molecules.

Abstract
In the title hydrated salt, C36H66N8O6+·6ClO4 -·1.5H2O, the asymmetric unit consists of a hexaprotonated [H6 L]6+ cation, five perchlorate anions in general positions, two on twofold rotation axes (one of which is disordered), and two water molecules of crystallization in general positions, one of them disordered around a twofold crystallographic axis. In the [H6 L]6+ cation, two strong intramolecular N-H⋯N hydrogen bonds occur, involving the N atoms of the oxadiazole ring as acceptors and the closest NH+ groups of each dipropylenetriamine unit. In the crystal, the [H6 L]6+ cations form channels along the a-axis direction, in which the perchlorate counter-ions and the water molecules are lodged. The crystal packing features a network of N-H⋯O and O-H⋯O hydrogen bonds involving the NH+ groups of the [H6 L]6+ cation, the perchlorate anions and the water molecules.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
