Trans-Bis(4-aminopyridine-κN)bis(succinimidato-κN)copper(II) dihydrate

The title compound, [Cu(C4H4NO2)2(C5H6N2)2]·2H2O, has its metal atom in a square-planar trans-[CuN4] coordination environment; the CuII atom lies on a center of symmetry. Both succinimidate and 4-amino­pyridine ligands behave as monodentate ligands, which coordinate through deprotonated imidate and pyridine (not amino) N atoms, respectively. The 4-amino­pyridine is the first ligand in such CuII complexes containing two different N atoms to take potentially different coordination modes.
