Bis[2-(methylamino)troponato]copper(II)

Abstract

In the title compound, [Cu(C8H8NO)2], a strictly square-planar geometry about the CuII metal atom is observed. Substitution of an O atom with a methyl-functionalized N atom does not significantly alter the bond distances and angles in the copper(II) complex when compared with a similar bis(troponato)copper(II) complex. π–π stacking is observed between the tropolone rings, with interplanar distances of 3.5039 (16) and 3.2933 (15) Å, respectively. Additional stabilisation of the structure is accomplished through C—H...O hydrogen-bonding interactions.
