Abstract

We report the synthesis of a series of mixed valence MnII/IV tetranuclear clusters [MnII2MnIV2O2(heed)2(EtOH)6Br2]Br2 (1), [MnII2MnIV2O2(heed)2(H2O)2Cl4]·2EtOH·H2O (2·2EtOH·H2O), [MnII2MnIV2O2(heed)2(heedH2)2](ClO4)4 (3), [MnII2MnIV2O2(heed)2(MeCN)2(H2O)2(bpy)2](ClO4)4 (4) and [MnII2MnIV2O2(heed)2(bpy)2Br4]·2MeOH (5·2MeOH). Clusters 1–5 are constructed from the tripodal ligand N,N-bis(2-hydroxyethyl)ethylene diamine (heedH2) and represent rare examples of tetranuclear Mn clusters possessing the linear trans zig-zag topology, being the first MnII/IV mixed-valent clusters of this type. The molecular clusters can then be used as building blocks in tandem with the (linear) linker dicyanamide ([N(CN)2]−, dca−) for the formation of a novel extended network {[MnII2MnIV2O2(heed)2(H2O)2(MeOH)2(dca)2]Br2}n (6), which exhibits a rare form of the 2D herring bone topology.
