Phase transitions are a common phenomenon in condensed matter and act as critical degree of freedom that can be employed to tailor the mechanical or electronic properties materials. Understanding fundamental mechanisms thermodynamics kinetics phase is, thus, at core modern materials design. Conventionally, studies have, large extent, focused on pristine bulk phases. However, realistic exist com...

in this paper, macrocyclic cobalt(ii) complexes [col1](no3)2.4h2o (1) and [col2](no3)2.2h2o (2) have been synthesized from the reaction of dialdehydes 1,2-bis(2-formylphenyl)ethane and 1,3-bis(2-formylphenyl)propane, co(no3)2.6h2o and 1,2-cyclohexanediamine with molar ration 1:1:1 in methanole and characterized by elemental analyses and ft-ir spectroscopy. then used as precursors for preparatio...
