One new complex of[Cu(pic)(Histindine)(OH2)]·2H2O(1)(picolinic acid,abbreviated as Hpic;Histindine,abbreviated as H2is)has been prepared at room temperature from the reaction of CuCl2·2H2O and picolinic acid,and characterized by X-ray analysis,IR.Crystal data for 1:CuC12H18N4O7,Mr=393.84, monoclinic, c2, a = 15.891 1(10), b = 6.402 3(4), c = 15.654 3(9)(A),β = 104.674(2)°,Z = 4,V = 1 540.71(16)(A)3, F(000) = 812, Dc = 1.698 g/cm-3,T = 293(2) K,μ(Mo-Kα) = 25.00 cm-1,λ(Mo-Kα) = 0.710 73(A).The structure was refined to R = 0.069 8 and Wr = 0.170 3 (unit weights) for 1832 observed reflections (I>2σ(I)). Cu(II) ion in the title complex is of penta-coordination, being chelated by pic- and His- and further coordinated by one water molecule.
