Two cyanide-bridged alternated 1 : 1 RuIII/MnIII complexes structurally characterized as single-chain containing co-crystallized bulk anions and cations have been successfully assembled from [Mn(TPP)(H2O)2]+ and [Ru(acac)2(CN)2]− blocks. Systematic investigation of their magnetic properties reveals typical single-chain magnet (SCM) behaviors for both of them.
