Abstract

Pyridin-2-ylmethanols (hmp) and 1, 3-propanediols have been proven to be successful ligands for constructing high-spin manganese clusters. In this work, both ligands are merged into one framework, resulting in a new tridentate ligand 4-chloro-2-(hydroxy(pyridin-2-yl)methyl)phenol. Its initial attempt in Mn coordination chemistry harvested a Mn^III dimer [Mn^III₂(L)₂(AcAc)₂] and a 2-D honeycomb network based on star-shaped [Mn^IIMn^III₃] tetramer {[Mn^IIMn^III₃(Na)_1.5(L)₆](OH)_0.5·(MeOH)_1.5}_n. The two clusters were characterized by single crystal X-ray diffraction, IR spectra, elemental analysis, and magnetic measurements. Magnetic studies revealed dominant ferromagnetic interactions within the Mn^III dimer and star-shaped [Mn^IIMn^III₃] tetramer unit.
