2-Amino-pyridinium bis-(pyridine-2,6-dicarboxyl-ato)ferrate(III).


ABSTRACT: In the title compound, (C(5)H(7)N(2))[Fe(C(7)H(3)NO(4))(2)] or [2-apyH][Fe(pydc)(2)], the asymmetric unit contains an [Fe(pydc)(2)](-) (pydc is pyridine-2,6-dicarboxyl-ate) anion and a protonated 2-amino-pyridine cation ([2-apyH](+)). The complex anion contains an Fe(III) atom within a distorted octahedral FeN(2)O(4) coordination geometry. N-H?O and C-H?O hydrogen bonding, offset ?-? stacking [centroid-centroid distance = 3.805?(13)?Å] and C=O?? inter-actions [3.494?(14)?Å] generate a three-dimensional network structure.

The complex anion contains an Fe(III) atom within a distorted octahedral FeN(2)O(4) coordination geometry. N-H⋯O and C-H⋯O hydrogen bonding, offset π-π stacking [centroid-centroid distance = 3.805 (13) Å] and C=O⋯π inter-actions [3.494 (14) Å] generate a three-dime  ...[more]
