Bis[4-(4-pyridyl)pyridinium] (4-carboxypyridine-2,6-dicarboxylato-κ3 O 2,N,O 6)(pyridine-2,4,6-tricarboxylato-κ3 O 2,N,O 6)ferrate(III) trihydrate

چکیده
In the title salt, (C(10)H(9)N(2))(2)[Fe(C(8)H(2)NO(6))(C(8)H(3)NO(6))]·3H(2)O, the Fe(III) atom is O,N,O'-chelated by dianionic and trianionic ligands in a slightly distorted octa-hedral coordination geometry. The cations and ferrate anions are linked into a layered structure; the layers are connected through the uncoordinated water mol-ecules into a hydrogen-bonded three-dimensional supra-molecular structure. One of the uncoordinated water molecules is disordered around an inversion centre and was refined with half-occupancy for each position.

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, [Cu(C(7)H(3)NO(4))(C(6)H(6)N(2)O)(H(2)O)], the coordination geometry of the Cu(II) atom can be described as distorted square pyramidal. The basal plane is defined by one N atom and two O atoms from the deprotonated pyridine-2,6-dicarboxyl-ate ligand, and a pyridyl N atom from the 4-pyridyl aldoxime ligand. The apical position is occupied by a water mol-ecule. O-H⋯O hydrog...
