Structure variation due to ligand flexibility: Syntheses and structures of the copper(II) complexes [Cu(APPy)] and [Cu-2(AEPy)(2)] where APPyH(2) = bis[3-(2-pyridinecarboxamido)propyl]methylamine and AEPyH(2) = bis[3-(2-pyridinecarboxamido)ethyl]methylamine
Two new pentacoordinate ligands containing two pyridine 2-carboxamide units connected by -(CH2)(n)-N(Me)-(CH2)(n)- links have been synthesized. The ligand with n = 3 affords a monomeric Cu(II) complex, while the one with n = 2 gives rise to a ligand-shared dimer.
