Tris(2-amino­pyridinium) hexa­chlorido­indate(III)

The Schiff base (E)-4-chloro-2-[(pyridin-2-yl­imino)­meth­yl]phenol was reacted with InCl(3)·4H(2)O, generating the title molecular salt, (C(5)H(7)N(2))(3)[InCl(6)]. The octa­hedral hexa­chlorido­indate(III) anion is located on an inversion centre, and one half of the anion and two crystallographically independent cations form the asymmetric unit. One of the cations is located on a twofold rotation axis and its intra-ring C and N atoms simulate this symmetry by exchanging their positions in statistical disorder. In the crystal, weak N—H⋯Cl hydrogen bonds and two types of π–π interactions with centroid–centroid separations of 4.047 (3) and 4.202 (3) Å are observed.
