Reassignment of the crystal space group of crystalline Pr[M(CN)6] · 5H2O (M = Cr, Fe, Co)

Refinement of the X-ray crystal structures of Pr[M(CN)6] · 5H2O (M = Cr, Fe, Co) enables their space group to be reassigned to P63/mmc. Spectral characteristics are reported for M = Cr and the distinction between the pentahydrate and tetrahydrate series is clearly made from assignments of the infrared spectra.
