Compartmental ligands. Part 9. Crystal and molecular structure of 6,11-dimethyl-7,10-diazahexadeca-5,11-diene-2,4,13,15-tetraone and of the related mononuclear copper(II) complex having N2O2 occupancy

Abstract

The crystal and molecular structures of 6,11-dimethyl-7,10-diazahexadeca-5,11-diene-2,4,13,15-tetraone and [6,11-dimethyl-7,10-diazahexadeca-5,11-diene-2,4,13,15-tetraonato(2–)N,N′,O⁴,O¹³]copper(II) are reported, together with a discussion of the changes made on metal incorporation into the free ligand.
