Synthesis, structure and spectral characterization of a discrete binuclearcopper (II) complex

lA discrete binuclear copper (TI) complex containing Cu2O2 unit has been sy nthesized by the reaction of Cu (ClO4)(2). 6H(2)O with 2-aminopyridine in t he CH3OH solution and characterized by X-ray diffraction study and IR spect roscopy. The crystal is monoclinic, space group: P2(1)/n, with unit cell pa rameters: a = 8.2952(2), b = 18.4633(3), c = 10.5049(2) Angstrom. beta = 10 8.965(1)degrees, V = 1521. 56(5) Angstrom (3), Z = 2, C22H30N8O10Cl2Cu2 M-r = 764.521 D-c = 1.669 Mg/m(3), F(000) = 780, mu (MoK alpha) = 8.60, T = 29 3(2)K, final R = 0.0623, wR = 0.1536 for 2660 observed reflections with I > 2. 0 sigma (I). The centrosymmetric complex Cu-2 (CH3O)(2) (C5H6N2)(4) (ClO 4)(2) comprises a pair of Cu(II) atoms bridged by two methanoxo- and N-coor dination 2-aminopyridine. The Cu(II). . . Cu(II) distance is 3.002(1) Angst rom.
