Comparison of copper imine and amine podates: geometric consequences of podand size and donor type

J. L. Coyle, A. Fuller, V. McKee and J. Nelson

Abstract: The imine podands tris[(2-nitrobenzylidene)aminoethyl]amine and tris[(2-nitrobenzylidene)aminopropyl]amine both stabilize copper(I), forming {tris[(2-nitrobenzylidene)aminoethyl]amine- [kappa] ⁴N}copper(I) perchlorate acetonitrile disolvate, [Cu(C₂₇H₂₇N₇O₆)]ClO₄·2CH₃CN, (II), and {tris[(2-nitrobenzylidene)aminopropyl]amine- [kappa] ⁴N}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-nitrobenzyl)aminoethyl]amine binds Cu^II and the resulting compound, chloro{tris[(2-nitrobenzyl)aminoethyl]amine- [kappa] ⁴N}copper(II) chloride ethanol solvate, [Cu(C₂₇H₃₃N₇O₆)Cl]Cl·C₂H₅OH, (IV), shows both intra- and intermolecular hydrogen bonding, which gives rise to RRS or SSR conformations in the podand strands rather than the expected pseudo-threefold symmetry.

Formula: [Cu(C₂₇H₂₇N₇O₆)]ClO₄·2CH₃CN, [Cu(C₃₀H₃₃N₇O₆)]ClO₄ and [Cu(C₃₀H₃₃N₇O₆)]ClO₄
