Scheme 1. Structure and synthesis of [Zn6-α-SbW9] (1) and [(Zn/W)2-β-SbW9] (2). The synthesis starts from the [SbW9] unit and the transition metal (TM) of choice. [Mn-β-SbW9] was used as precursor for the synthesis of the title compound, which was obtained by exchange of the manganese linker cations with zinc cations and β/α-isomerization of the precursor. Counter cations are omitted for clarity. Color legend: WO6, pink octahedra; 60° rotated WO6, ice blue octahedra; Sb, dark grey spheres; O, dark red spheres; Zn, light grey spheres; Mn, orange spheres; Cd, dark green spheres, W in the linking belt, dark blue spheres. Opda – o-phenylenediamine; 2,3-DAP – 2,3-diaminophenazine, ACN – acetonitrile.
