چکیده
The Ce(III) atom in the title compound, {[Ce(C(8)H(2)NO(6))(H(2)O)(5)]·4H(2)O}(n), is N,O,O'-chelated by the carboxyl-ate trianion and is coordinated by five water mol-ecules; a carboxyl O atom from an adjacent trianion bridges the Ce(III) atom, resulting in a chain running along the a axis. The nine atoms surrounding the metal atom comprise a tricapped trigonal-prismatic polyhedron. The coordinated and lattice water mol-ecules inter-act with each other and with the carboxyl O atoms by O-H⋯O hydrogen bonds, generating a three-dimensional network.

In the title compound, [Mn(C(8)H(2)NO(6))(H(2)O)(2)](n), each pyridine-2,4,6-tricarboxyl-ate (tpc) ligand bridges two Mn(II) ions with the formation of polymeric chains located on a twofold rotation axis. Each Mn(II) ion is coordinated by two O and one N atoms from one tpc ligand, two O atoms from another ligand and two water mol-ecules in a distorted penta-gonal-bipyramidal geometry. The Mn-N ...

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...
