چکیده
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.

In the centrosymmetric dinuclear complex anion of the title compound, (C(5)H(8)N(3))(2)[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)(2)]·4H(2)O, the Bi(III) atom is eight-coordinated in an N(2)O(6) environment and has a distorted bicapped trigonal-prismatic coordination environment. Extensive inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds lead to the stability of the crystal structure. Inter-acti...

The title compound, {(C(4)H(12)N(2))[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)]·H(2)O}(n) or {(pipzH(2))[Bi(2)(pydc)(4)(H(2)O)]·H(2)O}(n), where pydcH(2) is pyridine-2,6-dicarboxylic acid and pipz is piperazine, was obtained by reaction of Bi(NO(3))(3)·5H(2)O with (pipzH(2))(pydc-H)(2)·3H(2)O in a 1:2 molar ratio in aqueous solution. There are two independent Bi(III) atoms in the structure, one of which i...
