Abstract

The first use of pressure-tuning spectroscopy as a diagnostic tool in the evaluation of an intervalence transition band to determine the number of electrons transferred is described. The trinuclear complex [(CN)₅FeCNPt(NH₃)₄NCFe(CN)₅]^4- was subjected in solution to hydrostatic pressures from ambient to 1.5 kbar giving a ΔV^* = -5.7 ± 0.2 cm³ mol^-1. Calculated values from various models ranged from -5.6 to -6.7 cm³ mol^-1 assuming a one-electron transfer event and a negligible innersphere reorganizational energy compared with the apparently very large outer-sphere rearrangements that must occur.
