Single Crystal of a Prussian Blue Analog based on Rubidium Manganese Hexacyanoferrate

Abstract

Abstract A dark brown single crystal of rubidium manganese hexacyanoferrate, Rb 0.61 Mn[Fe(CN) 6 ] 0.87 ·1.7H 2 O, was obtained by the slow diffusion method. X‐ray single crystal analysis showed that this compound crystallized in the cubic system of space group $Fm{\bar 3}m$ with cell constants of a = b = c = 10.5354(4) Å, Z = 4, and R 1 = 0.0449. The CN groups bridge octahedral FeC 6 and MnN 0.87 O 0.13 . Rb and non‐coordinated water (so‐called zeolitic water) exist in the interstitial sites of the cubic lattice.
