The copper(II) complex with two didentate Schiff base ligands. The unique rearrangment that proceeds under alcohol vapor in the solid state to construct noninclusion structure
The complexation reaction of copper(II) ion and N-(m-hydroxyphenylene)salicylideneaminate (mhsa) in EtOH yields EtOH-inclusion and noninclusion crystalline samples, [Cu-(mhsa)(2)]center dot 2EtOH (1) and [Cu(mhsa)(2)] (2), respectively. The amorphous sample obtained by drying 1 rearranges to the noninclusion complex 2 under alcohol vapor in the solid state.
