3-(Amino-carbon-yl)pyridinium diaqua-bis-(pyridine-2,6-dicarboxyl-ato)bis-muthate(III) monohydrate.
The asymmetric unit of the ionic title compound, (C(6)H(7)N(2)O)[Bi(C(7)H(3)NO(4))(2)(H(2)O)(2)]·H(2)O or (acpyH)[Bi(pydc)(2)(H(2)O)(2)]·H(2)O, contains an [Bi(pydc)(2)(H(2)O)(2)](-) anion (where pydcH(2) is pyridine-2,6-dicarb-oxy-lic acid), a protonated 3-(amino-carbon-yl)pyridine as counter-ion, (acpyH)(+), and one uncoordinated water mol-ecule. The anion is an eight-coordinate complex with a square-anti-prismatic geometry around the Bi(III) atom. In the crystal, extensive O-H⋯O and N-H⋯O hydrogen bonds, as well as ion pairing, C=O⋯π inter-actions [O⋯centroid distance = 3.583 (5) Å], π-π stacking [centroid-centroid distance = 3.864 (3) Å], and C-H⋯π and C-H⋯O inter-actions, play an important role in the formation and stabilization of the three-dimensional supra-molecular structure.
