Abstract
The imine podands tris[-(2-nitro-benzyl-idene)-amino-ethyl]-amine and tris[-(2-nitro-benzyl-idene)-amino-propyl]-amine both stabilize copper(I), forming (tris[-(2-nitro-benzyl-idene)-amino-ethyl]-amine-kappa N-4)copper(I) perchlorate aceto-nitrile disolvate, [Cu(C27H27N7O6)]ClO4.2CH(3)CN, (II), and (tris[-(2-nitro-benzyl-idene)-amino-propyl]-amine-kappa N-4)copper(I) perchlorate, [Cu(C30H33N7O6)]ClO4, (VI), respectively. The larger propyl-based ligand is a poorer fit for the Cu-I ion. The reduced amine podand tris[-(2-nitro-benzyl)-amino-ethyl]-amine binds Cu-II and the resulting compound, chloro-(tris-[(2-nitro-benzyl)-amino-ethyl]-amine-kappa N-4)copper(II) chloride ethanol solvate, [Cu(C27H33N7O6)Cl]Cl.C2H5OH, (IV), shows both intra- and inter-molecular hydrogen bonding, which gives rise to RRS or SSR conformations in the podand strands rather than the expected pseudo-threefold symmetry.
