Three metal ion bridged self-assembled （SA） films of cis-di（thiocyanato）-bis（2,2＇-bipyridyl-4,4＇-dicarboxylate） ruthenium were fabricated and characterized by contact angle, UV spectra, cyclic voltammetry and XPS. Their photoinduced electron transfer properties （PETP） were examined. Among the titled systems, the highest steady anodic photocurrent of 1773-1843 nA/cm^2 and the highest quantum yield of 3.2% were achieved. The effects of incident light intensity, bias voltage, and electron donor were also studied. The possible mechanism of electron transfer was proposed. The results reveal that different metal ion in SA films could affect significantly the photoinduced electron transfer property. Our experimental results clearly show that bridging metal ions can play both functional and structural roles in these self-assembled systems. This method of forming functional films can provide a new approach to regulate the property of similar systems.

The dinuclear Schiff base cadmium（Ⅱ） complex [Cd2（C10H15N3）2（N3）2 （μ1,1-N3）2] was prepared and characterized by elemental analysis, IR spectrum, and single-crystal X-ray dif- fraction. The crystal belongs to the monoclinic system, space group P21/n with a = 10.819（2）, b = 11.058（2）, c = 12.766（3）A, β = 102.456（2）°, V = 1491.3（7）A^3, Z = 2, Dc = 1.665 g/cm^3, Mr = 747.42, λ（MoKα） = 0.71073 （A）, μ = 1.470 mm^-1, F（000） = 744, R = 0.0307 and wR = 0.0584. A total of 3420 unique reflections were collected, of which 2575 with Ⅰ 〉 2σ（Ⅰ） were observed. There is a crystallographic inversion centre at the midpoint of the two metal atoms in the complex. Each CdⅡ atom in the complex is in a distorted octahedral coordination. The molecules in the crystal are linked through the intermolecular hydrogen bonds of N-H…N and C-H…N, forming a three- dimensional network.

Two novel coordination polymers [Cd（NiL）（aipt）]（1） and [Mn（nipt）（NiL）2]？H2O（2）（NiL, H2L=2,3-dioxo- 5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,13-dien, H2aipt=5-aminoisophthalic acid, H2nipt=5-nitroisoph- thalic acid） were hydrothermally synthesized and characterized by single-crystal X-ray diffraction. Compounds 1 and 2 consist of different 1D chains including both oxamide and 5-aminoisophthalate or 5-nitroisophthalic bridge. And all these chains were further interlinked via hydrogen bonds, resulting in a 2D architecture in compounds 1 and 2.

A novel end-to-end azido-bridged polynuclear Schiff-base copper（II） complex, [Cu（C12H15Br2N2O）（N3）]n, was prepared and characterized by elemental analysis, IR spectra, and single-crystal X-ray diffraction. The crystal belongs to the orthorhombic system, space group Pbcn with a = 24.588（5）, b = 10.377（2）, c = 13.022（3） A, V= 3322.6（12） A^3, Z = 8, Dc = 1.874 g/cm^3, Mr = 468.65, λ（MoKa） = 0.71073 A,μ = 6.130 mm^-1, F（000） = 1832, R = 0.0637 and wR = 0.1176. The Cu atom in the complex is five-coordinated in a square pyramidal geometry by three donor atoms of the Schiff-base ligand, and two N atoms from two bridging azide ligands. The [2,4-dibromo-6-[（3-dimethylaminopropylimino）methyl]phenolato]copper（II） units are linked by the bridging azide ligands, giving zigzag polymeric chains with backbones of the [--Cu-N-N-N--Cu]n type running along the b axis.
