چکیده

The cation of the salt, C(18)H(18)N(2)O(2) (2+)·2NO(3) (-), lies about a twofold rotation axis. The pyridinium ring is almost coplanar with the phenyl-ene ring [dihedral angle between rings = 5.69 (9)°]. The crystal structure shows π-π stacking inter-actions [centroid-centroid distance = 3.70 (1) Å] between the pyridinium rings and the phenyl-ene rings, generating a linear chain structure. The cation also forms two N-H⋯O hydrogen bonds to two nitrate groups.

In the title salt, {(C(10)H(11)N(3))[V(4)O(8)(PO(4))(2)]}(n), cubane-like [V(4)O(8)](4+) clusters are connected by phosphate anions into anionic [V(4)P(2)O(16)](n) (2n-) layers. These aggregate into the three-dimensional structure via N-H⋯O hydrogen-bonding mechanisms imparted by 4,4'-imino-dipyridinium dications situated between the layers.
