Abstract

The syntheses, crystal structures and magnetochemical characterization are reported for two new mixed-valent manganese complexes, [Mn^II ₂Mn^III ₂(H₂O)₂(hmp)₆(NO₃)₂][Mn^II(NO₃)₃hmpH]₂ (1) and, [Mn^II ₂Mn^III ₄O₂(hmp)₄(hmpH)₂(EtC(Me)₂COO)₄Cl₂](EtC(Me)₂COO)₂ (2) incorporating the anion of 2‑hydroxymethyl pyridine. Complexes were further characterized by elemental analysis, IR & UV–Visible spectroscopy, single-crystal X-ray diffraction and thermogravimetric analysis. Variable temperature, solid-state direct current (dc) magnetization studies were carried out on both the complexes 1 and 2 in the 5.0–310 K range, and they established the complexes to have ground state spin values of S = 9 for 1 and S = 4 for 2.
