Abstract
Polynuclear coordination clusters can be readily arranged in cluster-based coordination polymers (CCPs) by appropriate bridging linkers. This review provides an overview of our recent developments in exploring structurally well-defined Mn/Fe-oxo pivalate and isobutyrate building blocks in the formation of CCPs assemblies with an emphasis on synthetic strategies and magnetic properties.
Highlights
Cluster-based coordination polymers (CCPs) have received significant attention over the past decade due to their promising potential as multifunctional materials for technological and industrial applications [1,2,3,4,5,6]

CCPs are constructed from metal coordination clusters that are bridged by polytopic organic ligands forming multidimensional systems such as one-dimensional (1D) chains, two-dimensional (2D) layers and three-dimensional (3D) metal–organic frameworks (MOFs) [7]
Summary
Cluster-based coordination polymers (CCPs) have received significant attention over the past decade due to their promising potential as multifunctional materials for technological and industrial applications [1,2,3,4,5,6]. Trinuclear oxo-centered carboxylate coordination clusters of general composition [M3(μ3-O)(O2CR)6(L)3]+/0 (where L = a neutral terminal ligand) are the most frequently used building blocks in the construction of CCPs. For assembling 1D oxo-trinuclear Mn/Fe CCPs, several synthetic strategies have been explored, e.g., using simple soluble metal salts or well-known pre-designed “basic carboxylate”, e.g., μ3-oxo trinuclear Mn/Fe carboxylate clusters. Mixing a hot ethanol solution of hexamethylenetetramine (hmta) with MnII isobutyrate in tetrahydrofuran yields the chain coordination polymer {[Mn3O(is)6(hmta)2]·EtOH}n (where His = isobutyric acid) (1) [29] One of the fascinating Mn oxo-carboxylate clusters used as building blocks in the construction of CCPs are hexanuclear clusters [Mn6O2(O2CR)10(L)4] (where L = neutral monodentate ligand) with a central {Mn6O2} core.
