Abstract
Reaction of hexaaquacopper(II) perchlorate with n-methyl-2-hydroxypyridine generated a family of [(n-methyl-2-pyridone)xCu](ClO4)2 complexes: [(3-methyl-2-pyridone)6Cu](ClO4)2 (1), [(4-methyl-2-pyridone)6Cu](ClO4)2 (2), [(5-methyl-2-pyridone)6Cu](ClO4)2 (3), [(5-methyl-2-pyridone)4(H2O)2Cu](ClO4)2.2(5-methyl-2-pyridone) (4), and [(6-methyl-2-pyridone)4Cu(ClO4)2] (5). Variable temperature X-ray structural analysis reveals a mixture of elongation and compression Jahn-Teller or Jahn-Teller-like distortions. Compound 1 undergoes a temperature dependent phase transition from a Jahn-Teller elongated structure to a Jahn-Teller compressed structure. © 2026 Informa UK Limited, trading as Taylor & Francis Group.
