Tris(2-amino-pyridinium) hexa-chlorido-indate(III).
The Schiff base (E)-4-chloro-2-[(pyridin-2-yl-imino)-meth-yl]phenol was reacted with InCl(3)·4H(2)O, generating the title molecular salt, (C(5)H(7)N(2))(3)[InCl(6)]. The octa-hedral hexa-chlorido-indate(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.
