Abstract

The crystal structure of the title complex, [Cu(C5H7O2)I(C10H8N2)], in the space group P1 with Z = 4, is stabilized by π-π interactions and weak C-H···I interactions. The presence of two molecules in the asymmetric unit is associated with different intermolecular π-π interactions between two symmetry-related molecules of each type.

Keywords: Casiopeinas; copper complex; crystal structure; halogen bonds; π–π interactions.
