The cover picture shows a new wheel‐shaped hexanuclear manganese(III) complex, [LiMn 6 (L) 6 ]OH·2MeCN·4MeOH·1.5H 2 O (LiH 2 L = lithium 2‐{[bis(2hydroxyethyl)amino]methyl}‐4‐methylphenate). The structure of [LiMn 6 (L) 6 ]OH was refined by single crystal X‐ray diffraction with the monoclinic space group P 21 /n , [Z = 4, a = 1926.2(4) pm, b = 2206.3(4) pm, c = 2178.3(4) pm, and β = 105.93(3)°] and the molecule lies on a crystallographic center of symmetry. Crystal structure shows that six octahedrally coordinated manganese(III) ions define a ring and are linked by twelve bridging oxygen atoms from alkoxo groups. The resulting [Mn 6 (OCH 2 ) 12 ] skeleton has the remarkable property of acting as a host for a octahedrally coordinated lithium ion in the center of the ring, which form the wheel structure. More details are discussed in the article by Pei‐Pei Yang et al. on pp. 567 ff.
