✦ Synopsis

Synthesis, spectroscopy, and crystal structures of [Cu(ca 2 en) 2 ]ClO 4 (1) and [Cu(ca 2 en)(PPh 3 ) 2 ]ClO 4 (2) (ca 2 en N,N'-bis(trans-cinnamaldehyde)ethylenediimine) are reported. Compound 1 crystallizes in the orthorhombic space group Pbca, with a 12.5647( ), b 21.8203(11), c 27.992(2) ä, V 7674.3(7) ä 3 , Z 8. Compound 2 crystallizes in the triclinic space group P1 ≈ , with a 13.0540( ), b 14.2935(13), c 14.9863(13) ä, a 84.130(2), b 69.761(2), g 87.749(2)8, V 2609.8(4) ä 3 , Z 2. The coordination polyhedron about the Cu I center in the two complexes is best described as a distorted tetrahedron. The 1 H-NMR and electronic spectra of these complexes are also reported and discussed. The cyclic voltammetry of the complexes indicate a quasireversible redox behavior for complex 1 (E 1/2 0.51 V). However, complex 2 displays an irreversible oxidation wave at 0.91 V. A weak emission is observed for complex 2 in CHCl 3 at room temperature.
