Cyclic voltammetric studies of clusters(C_6H_5-C_2C_6 H_4-R-p)Co_2(CO)_(6-n) L_n[n=0,2; L=PPh_3,P(OEt)_3] and(RCH_2C)_2Co_2(CO_4)(PPh_3)_2 on Pt electrode are described. The primary reduction(0/-1)and oxidation (+1/0) steps are considered as a mono-electron process for all clusters. For the clusters (C_6H_5C_2C_6H_4-R-P)Co_2(CO)_6, a good linear relation between reduction poten- tial EF_p^(red) and Hammett constant σp of R in the clusters is found. For the clusters(RC_2R′)Co_2(CO)_4L_2, their radical anions are extremely unstable at room temperature and fragment into a series of mono- nuclear species, one of which is(RC-3R′)Co(CO)_2PPh_3. The reaction of radical anions of (RC_2R’)- Co_2(CO)_(6-n) (PPh_3)_n(n=0,2) with PPh_3 also produces mononuclear species (RC_2R’)Co(CO)_2PPh_3 which has been detected by means of cyclic voltammetry and ESR. The influence of R on redox pro- perties of clusters is discussed.

A new complex [Ni（phen）（mal）（H2O）2]·3H2O （phen = 1,10-phenanthroline, real^2- = malonic acid） has been synthesized by the reaction of nickel nitrate, phen and malonic acid. EA, IR spectra and X-ray single-crystal diffraction were carried out to determine the composition and crystal structure of the title complex. Crystal data： monoclinic system, space group P2/c,α = 8.937（3）, b = 12.163（5）, c = 9.725（3） A,β = 119.36°, C15H19N2O9Ni,Mr= 430.03, Z = 2, F（000） = 446, V= 921.3 A3, Dc = 1.550 g/cm^3, μ= 1.104 mm^-1, -10≤h≤10, -12≤k≤ 14, -11≤1≤7, R = 0.0261 and wR = 0.0609 for 4376 （Rint = 0.0203） independent reflections and 1631 observed ones （I 〉 2σ（I））. Ni（Ⅱ） exhibits an octahedral coordination geometry, with hydrogen bonds and π-π interactions stabilizing the whole structure. UV spectrum of the complex interacting with protamine DNA indicates that the title compound interacts with DNA via insertion mode with bonding constant Kb of 1. 11 × 10^4.

The structure of the title compound consisting of N,N-1,3-dibenzyl-benzimidazole ion, Cl- anion and hydrate was determined by X-ray diffraction method. It crystallizes in the triclinic system, space group P with a = 9.320(2), b = 9.850(2), c = 11.510(2) ? = 68.75(3), = 80.57(3), = 70.20(3)?

The total reflections were 3462 and 3244 (Rint = 0.0206) were independent, of which 1666 were observed with I > 2s(I). The planes of benzyl group are nearly perpendicular to each other. The water molecules with Cl-anions and C(8) atom are involved in hydrogen bonds and interactions, and - stacking interaction exists obviously between the adjacent phenyl and imidazole rings. The title complex forms a three-dimensional network throughout the structure through these hydrogen bonds and interactions.

The coordination polymer, [Mn3（bpta）2（bip）2], （H3bpta = biphenyl-3,3＇,5-tricar- boxylic acid, bip = 2,6-bis（imidazole-1-yl）pyridine）, has been synthesized under hydrothermal con- ditions and characterized by elemental analysis, FT-IR, XRD, TGA and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 14.919（3）, b = 9.780（2）, c = 20.352（7） A, V = 2344.4（10） A3, Z= 2, C52H32Mn3N10012, Mr = 1153.70, Dc = 1.634 g/cm3, p（MoKa） = 0.876 mm-1, F（000） = 1170, the finalR = 0.0605 and wR = 0.1177. The complex forms a 2D layer with trinuclear Mn（II） units and further assembles into a 3D supramolecular network structure through C-H..＇O hydrogen bonding and C-H...π interactions. Moreover, the negative J value indicates the presence of antiferromagnetic coupling between the Mn（II） ions within a trinuclear unit.

Over the years, there has been a great deal of interest in developing artificial enzymesthat hydrolyse amide bond of peptides and proteins. Recently, we found that Pd(Ⅱ)complexes bind to the sulfur atom of S-methylcysteine or methionine in peptides andpromote the selective hydrolysis of the adjacent amide bond on the carboxyl side of an-choring side chain. The half-lives of certain hydrolysis reactions are as short as

The title compound [ClC6H4COCH2(C2H2N3)] has been prepared and characterized by elemental analysis, IR spectrum and X-ray studies. It crystallizes in the monoclinic system, space group P21/c with Mr = 221.64 (C10H8ClN3O), a = 13.420(3), b = 9.720(2), c = 7.900(2) ? b = 92.00(3)? V = 1029.9(4) 3, Z = 4, Dc = 1.429 g/cm3, F(000) = 456, m = 0.345 mm-1, R = 0.0435 and wR=0.0894. The total reflections were 1949 and the independent ones were 1805 (Rint=0.0340), of which 800 were observed with I > 2s(I). The crystal structure consists of a-(1,2,4-triazol-1H- yl)-r-chloro-acetophenone. The existence of p conjugated systems in the molecule affects partly the bond lengths. The triazole and phenyl rings form the dihedral angle of 77.34. The molecules of the title compound connect to each other through extensive hydrogen bonds to form a two-dimensional structure. Elemental analysis and IR spectra are in good agreement with the structure data.
