Abstract

Abstract : A yellow crystal with {FeII4O4 } cubes is modified to a black crystal with {FeIII4O4 } cubes via a SC–SC transformation. Abstract : The very rare occurrence of a gas–solid chemical reaction has been found to take place on a molecule within a compact non-porous crystal without destroying its long-range structural order and retaining similar crystal structures when yellow crystals of FeII4( mbm )4 Cl4 (MeOH)4 were exposed to air to give black [FeIII4( mbm )4 Cl4 (OH)4 ]·2H2 O. The latter cannot be synthesised directly. The original cluster underwent an exchange of methanol to hydroxide, an oxidation of Fe(ii ) to Fe(iii ), a change in stereochemistry and hydration while the packing and space-group remained unaltered.
