Abstract:A Cu(II) complex [CuCl(C19H20N40)]ClO4 1 containing hydroxymethyl substituted TPA (TPA = tris(2-pyridylmethyl)amine) was prepared. It crystallizes in monoclinic, space group P2(1)/c with a = 11.7628(2), b = 13.0083(3), c = 15.11280(10) Angstrom, beta = 108.724(2)degrees, V = 2190.09(7) Angstrom(3), M-r = 518.83, Z = 4, T = 293 (2) K, D-c = 1.574 g/cm(3), mu = 1.280 mm(-1), F(000) = 1060 and S = 1.085. The final R = 0.0543 and wR = 0.1433 for 2693 observed reflections with I >2sigma(I). The penta-coordinated copper (H) complex. assumes an approximate square pyramidal geometry. Cyclic voltammetry measurement of the complex showed a quasi-reversible Cu-II/Cu-I redox couple with E-1/2 -0.467 v and DeltaE = 68 mv.
