Tris(2-aminopyridinium) hexachloridoindate(III)

چکیده
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.

In the title hybrid salt, (C(5)H(7)N(2))[Cr(H(2)O)(2)(C(2)O(4))(2)], the Cr(III) ion is coordinated in a slightly distorted octa-hedral environment by four O atoms from two oxalate ligands in the equatorial plane and by two water O atoms in the axial sites. The 2-amino-pyridinium cation is disordered over two sets of sites in a 0.800 (7):0.200 (7) ratio. In the crystal, N-H⋯O and O-H⋯O hydrogen...

In the non-centrosymmetric structure of the title compound, (C(5)H(7)N(2))[Cr(C(2)O(4))(2)(H(2)O)(2)]·H(2)O, the Cr(III) ion has a slightly distorted octa-hedral coordination environment defined by two chelating oxalato ligands in equatorial positions and two water mol-ecules in axial positions. An extensive three-dimensional network of hydrogen bonds involving all the water mol-ecules, the 4-a...
