The cover picture shows the multilayer spin arrangement in [Mn(Cp*) 2 ][Ni(α‐tpdt) 2 ] (α‐tpdt = 2,3‐thiophenedithiolate). The crystal structures of the salts [M(Cp*) 2 ][Ni(α‐tpdt) 2 ] (M = Fe, Mn and Cr) consist of alternating layers that are composed of arrangements of parallel mixed chains. The chains in neighboring layers are perpendicular. The arrangement between the chains and the magnetic anisotropy of the cations in case of the salt [Mn(Cp*) 2 ][Ni(α‐tpdt) 2 ] lead to a degenerate ground state and to a frustrated magnetic behavior, which can be associated with the absence of long‐range order between the ferromagnetic layers. Details are discussed in the article by M. Almeida, V. Gama et al. on p. 5327 ff.
