چکیده
In the binuclear centrosymmetric title compound, [In(2)(C(7)H(3)NO(4))(2)(C(7)H(4)NO(4))(2)(H(2)O)(2)]·4H(2)O, which contains both pyridine-2,3-dicarboxyl-ate and 3-carb-oxy-pyridine-2-carboxyl-ate ligands, the In(III) atom is six-coordinated in a distorted octa-hedral geometry. One pyridine ligand is N,O-chelated while the other is N,O-chelated and at the same time bridging to the other via the second carboxyl group. In the crystal, an extensive O-H⋯O hydrogen-bonding network, involving the coordinated and lattice water mol-ecules and the carboxyl groups of the ligands, together with C-H⋯O and π-π inter-actions [centroid-centroid distance = 3.793 (1) Å], leads to the formation of a three-dimensional 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...

In the title compound, [Ce(C(7)H(3)NO(4))(C(7)H(4)NO(4))(H(2)O)(5)]·4H(2)O, the Ce(3+) ion is nine-coordinated by two O atoms and two N atoms from one single and from one double deprotonated pyridine-2,5-dicarboxyl-ate ligand and five water mol-ecules in a distorted monocapped square-anti-prismatic geometry. In the crystal, extensive O-H⋯O hydrogen-bonding inter-actions result in a three-dimens...
