Tris(2,2'-bipyridine-κ(2)N,N')cobalt(III) bis-[bis-(pyridine-2,6-dicarboxyl-ato-κ(3)O(2),N,O(6))cobaltate(III)] perchlorate dimethyl-formamide hemisolvate 1.3-hydrate.

ABSTRACT: In the title compound, [Co(C(10)H(8)N(2))(3)][Co(C(7)H(3)NO(4))(2)](2)(ClO(4))·0.5C(3)H(7)NO·1.3H(2)O, the Co(III) atom in the complex cation is pseudoocta-hedrally coordinated by six N atoms of three chelating bipyridine ligands. The Co(III) atom in the complex anion is coordinated by two pyridine N atoms and four carboxyl-ate O atoms of two doubly deprotonated pyridine-2,6-dicarboxyl-ate ligands in a distorted octa-hedral geometry. One dimethyl-formamide solvent mol-ecule and two water mol-ecules are half-occupied and one water mol-ecule is 0.3-occupied. O-H⋯O hydrogen bonds link the water mol-ecules, the perchlorate anions and the complex anions. π-π inter-actions between the pyridine rings of the complex anions are also observed [centroid-centroid distance = 3.804 (3) Å].
