Abstract

The chemisorption of sulfur dioxide (SO₂) on the Hofmann-like spin crossover porous coordination polymer (SCO-PCP) {Fe(pz)[Pt(CN) ₄]} has been investigated at room temperature. Thermal analysis and adsorption-desorption isotherms showed that ca. 1 mol of SO₂ per mol of {Fe(pz)[Pt(CN)₄]} was retained in the pores. Nevertheless, the SO₂ was loosely attached to the walls of the host network and completely released in 24 h at 298 K. Single crystals of {Fe(pz)[Pt(CN) ₄]}·nSO₂ (n ≈ 0.25) were grown in water solutions saturated with SO₂, and its crystal structure was analyzed at 120 K. The SO₂ molecule is coordinated to the Pt^II ion through the sulfur atom ion, Pt-S = 2.585(4) Å. This coordination slightly stabilizes the low-spin state of the Fe^II ions shifting the critical temperatures of the spin transition by 8-12 K. DFT calculations have been performed to rationalize these observations.
