Figure 3
Detail of (I)[link], showing a perchlorate anion approaching atom Cu2, giving rise to a distorted octa­hedral arrangement. The same O atom (O1A) also accepts a hydrogen bond from the bicarbonate anion. To accommodate the perchlorate anion, the cryptate is `flattened' at the Cu2 end, reflected most clearly in the N6—Cu2—C7 and N2—Cu1—N3 angles (Table 1[link]). H atoms bound to C and N atoms have been omitted.
