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 MnIII dimer [MnIII2(L)2(AcAc)2] and a 2-D honeycomb network based on star-shaped [MnIIMnIII3] tetramer {[MnIIMnIII3(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 MnIII dimer and star-shaped [MnIIMnIII3] tetramer unit.
