The crystal structure of [pyda·H][Tl(pydc)2(H2O)]·4H2O, (pyda·H = 2,6-diaminopyridinum), (pydc = 2,6-pyridinedicarboxylate), has been determined by the X- ray diffraction method. This compound crystallizes in the triclinic system, space group P1, with two molecules per unit cell. The unit cell dimensions are a = 6.614(6), b = 13.430(12), c = 14.015(13)A, α = 68.908(16), β = 77.020(18), γ = 82.007(18)°, V = 1129.4(18)A3. The final R value is 0.0419 for 4965 measured reflections. The resulting Tl(III) complex forms a crystal in which the thallium atom is at the center of a distorted pentagonal bipyramidal arrangement consisting of six donor atoms of the two tridentate ligands of [pydc]2- and one water molecule. There is also one [pyda·H]+ unit as a counter ion.
