چکیده
The title compound, C(22)H(20)N(2)O(2) (2+)·2ClO(4) (-), was synthesized by the reaction of naphthalene-2,6-diol with pyridine-4-carbaldehyde, 4-picolylamine and perchloric acid. There is a centre of symmetry at the mid-point of the central C-C bond of the cation. The two pyridine rings are parallel to each other, and the dihedral angle between the naphthalene ring system and the pyridine ring is 80.68 (11)°. All the bond lengths and angles are normal. Classical inter-molecular O-H⋯O and N-H⋯O hydrogen bonds connect cations and anions, forming a one-dimensional chain structure.

In the title compound, C(26)H(32)N(8)O(6) (2+)·2BF(4) (-), the cation is built up from four fused rings, viz. two nearly planar imidazole rings and two triazine rings exhibiting chair conformations. One eth-oxy group is disordered between two positions in an approximate ratio 3:2. The F atoms of the two anions are each rotationally disordered between two orientations in the same 3:2 ratio. The ...
