Resumen:
The [OsIII(CN)6]3- anion is prepared by chemical oxidation in aqueous solution and isolated as yellow prisms of [Ph4P]3[OsIII(CN)6]·6H2O (1). This species crystallizes in the triclinic space group P with cell parameters a = 13.7609(11) Å, b = 16.2275(13) Å, c = 17.0895(14) Å, = 91.4040(10), = 109.3600(10), = 102.3970(10), V = 3497.4(5) Å3, and Z = 2. The slightly distorted octahedral moiety displays Os-C and C-N bond lengths that average 2.058 and 1.146 Å, respectively. Spin-orbit-coupling splitting of the ground-state term dominates the NIR region of the electronic spectrum and the magnetic behavior of 1. The experimental information points to higher spin delocalization over the coordinated cyanides than in [FeIII(CN)6]3-.
