The 18H42N42+·2ClO4−, reveals that protonation has occurred at diagonally opposite amine N atoms. Intramolecular N—H⋯N hydrogen bonds stabilize the conformation of the dication. In the crystal, the dications are bridged by perchlorate ions via N—H⋯O hydrogen bonds into supramolecular chains propagating along the c axis and weak C—H⋯O interactions cross-link the chains.

The compound 3,10-C-meso-3,5,7,7,10,12,14,14—octamethyl-4,11-diaza-1,8-diazoniacyclotetradecadiene (Curtis et al., 1969), on reduction with NaBH4, yields an isomeric mixture of saturated macrocycles, the Me8[14] anes, which have been resolved into three distinct isomers (Bembi et al., 1989). During synthesis of Fe(III) complex of one of the isomers, LC (Bembi et al., 1989), this isomeric ligand on heating with slightly acidic methanolic solution of Fe2(ClO4)3.6H2O in the ratio of 1:2, followed by cooling and slow evaporation at room temperature for a few days produced yellow-orange prisms of (I).
All N– and C-bound H atoms were allowed to ride on their parent atoms at N–H and C–H distances of 0.88–0.92 Å and 0.92–1.00 Å, respectively, and with Uiso(H) values of 1.2–1.5Ueq(parent atom).
The title salt (I) was characterized during studies of macrocyclic ligands of this type as well as their transition metal complexes (Benson et al., 2006; Roy et al., 2006; Hazari et al., 2008; Roy et al., 2008). The
of (I) comprises one di-protonated macrocyclic ligand and two perchlorate anions, Fig. 1. The observed conformation and pattern of protonation (i.e. at the diagonally opposite N1 and N8 atoms) in the di-cation conforms to expectation (Hazari et al., 2008). The presence of N–H···N hydrogen bonds within the cavity is noted, Table 1. The remaining N–H groups form N–H···O hydrogen bonds to perchlorate-O atoms, Table 1. The perchlorate ions serve to bridge the cations to form a supramolecular chain along the c axis and connections between these, i.e. via C–H···O contacts, lead to the formation of a supramolecular layer in the ac plane. Layers stack along the b axis, Fig. 3.For background to macrocycles and for related structures, see: Benson et al. (2006); Roy et al. (2006, 2008); Hazari et al. (2008). For the synthesis, see: Curtis et al. (1969); Bembi et al. (1989).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title salt (I) was characterized during studies of macrocyclic ligands of this type as well as their transition metal complexes (Benson et al., 2006; Roy et al., 2006; Hazari et al., 2008; Roy et al., 2008). The asymmetric unit of (I) comprises one di-protonated macrocyclic ligand and two perchlorate anions, Fig. 1. The observed conformation and pattern of protonation (i.e. at the diagonally opposite N1 and N8 atoms) in the di-cation conforms to expectation (Hazari et al., 2008). The presence of N–H···N hydrogen bonds within the cavity is noted, Table 1. The remaining N–H groups form N–H···O hydrogen bonds to perchlorate-O atoms, Table 1. The perchlorate ions serve to bridge the cations to form a supramolecular chain along the c axis and connections between these, i.e. via C–H···O contacts, lead to the formation of a supramolecular layer in the ac plane. Layers stack along the b axis, Fig. 3.
