Palladium(II) Halide Complexes I. Stabilities and Spectra of Palladium(II) Chloro and Bromo Aqua Complexes

• Stability constants, βn, n = 1, 2, 3, 4, for the chloro and bromo complexes of palladium(II) have been calculated, using a least squares programme, from spectrophotometric measurements at 222, 234.5 and 279 nm (chloride) and at 247, 265, and 332 nm (bromide). The following values of lg(βn/M−n) were obtained: 4.47±0.01, 7.76±0.04, 10.17±0.07, and 11.54±0.09 (chloride) and 5.17±0.02, 9.42±0.04, 12.72±0.06, and 14.94±0.08 (bromide). Spectra of the species PdXn(H2O)4−n2−n, n = 0, 1, 2, 3, 4; X = Cl, Br, have been determined in the wave length region 210 to 600 nm. The temperature was 25.0°C and the ionic medium 1.00 M perchloric acid.
