The compound crystallizes in the orthorhombic system, space group Pbca with a = 8.9849(10), b = 13.2699(15), c = 22.975(2) A ,V= 2739.3(5) A^3, Mr= 255.31, Z= 8, F(000) = 1088, Dc = 1.238 g/cm^3, T= 293 K, μ = 0.082 mm^-1, λ = 0.71073 .A, the final R = 0.0596 and wR = 0.1575 for 1934 observed reflections with I 〉 2σ(I). The complex was valued for its antimicrobial activity against bacterial strands using the agar diffusion method, and found to be active against the four test bacterial organisms.展开更多

This method is very simple. The average size of the Pd particles in the Pd/C catalyst prepared with the improved complex reduction method is as small as about 2.1 nm and the Pd particles in the Pd/C catalyst possess an excellent uniformity. The Pd/C catalyst shows a high electrocatalytic activity and stability for the formic acid oxidation.展开更多
The title complex [Fe(L-trp)2(HL-trp)2]n (L-trp = L-tryptohan or 2-amino-3-(1H -indol-3-yl)-propanoic acid) has been formed by a hydrothermal method involving hexaaquacobaltous perchlorate and L-tryptophan.

The product was characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P211c, with a = 19.828(3), b = 5.4233(14), c = 9.2796(16) A, β= 97.691(2)°, V = 988.9(3) A3, Z = 2, Mr = 462.29, Dx = 1.553 g/cm3, F(000) = 480,/a = 0.802 mm^-1, the final R = 0.0399 and wR = 0.0930 for 1738 observed reflections with I 〉 2σ(/). The structural analysis shows that the complex assumes a two-dimensional double chain plane structure.展开更多
