cis- and trans-bis(benzoylacetonato)pyridinecopper(II): co-crystallisation of isomers and reversible pyridine loss with retention of crystallinity
Artikel i vetenskaplig tidskrift, 2007

The pyridine adduct of bis(benzoylacetonato-O, O') copper(II) crystallises in both its cis- and trans-isomers within the same crystal. Copper( II) exhibits square pyramidal coordination geometry in both isomers with weak coordination of pyridine. The square planes of the isomers are mutually orthogonal, forming a square grid, in the channels of which the pyridine molecules are stacked, approximately perpendicular to the c-axis. Pyridine is readily lost from crystals unprotected by pyridine solvent, forming a crystalline powder. This powder absorbs pyridine vapour to reform microcrystalline bis(benzoylacetonato) pyridine-copper(II).
