Two supramolecular compounds [Fe(2,2′-bipy)3]2[ (Cl)] · 4.67H2O (1) and [Ni(enMe)3]2[ (Cl)] · 2H2O (2) have been prepared under hydrothermal conditions and characterized by elemental analyses, IR, TGA, ESR, magnetic properties, and single crystal X-ray diffraction analyses. Crystal data for 1: tetragonal, I-42d, a = 13.6043(19), b = 13.6043(19), c = 50.544(10) Å, V = 9354(3) Å3; for 2: hexagonal, P6(3)/m, a = 12.6046(12), b = 12.6046(12), c = 22.563(5) Å, V = 3104.4(7) Å3. Compound 1 is constructed from cations [Fe(2,2′-bipy)3]3+, polyoxovanadates [ (Cl)]6−, and water molecules. Compound 2 is composed of cations [Ni(enMe)3]2+, clusters [ (Cl)]8−, and water molecules. There are hydrogen-bonding interactions between polyoxovanadates, organic moieties, and/or water molecules in 1 and 2, forming different 2-D layered networks.

Abstract An attempt has been made to enhance the tribological properties of Mg–11Y–2·5Zn alloy by laser surface melting with a 6 kW continuous wave CO2 laser processing system. The microstructure and microhardness of the surface layer on Mg–11Y–2·5Zn alloy were characterised using X-ray diffractometer, laser microscopy and Vickers hardness indentation. The laser surface melted zone consisted of fine dendrites and coarse dendrites growing epitaxially from the liquid/solid interface. Microhardness was improved from 69–70 HV for the substrate to 77–83 HV for the fine dendritic microstructure. The friction and wear characteristics were investigated using a pin on disc apparatus. The coefficient of friction curve of the laser surface melted specimen was similar to that of the untreated specimen. Laser surface melted Mg–11Y–2·5Zn alloy exhibited good wear resistance, which has been explained by refinement of microstructure in the melted zone. Four wear mechanisms including abrasion, delamination, thermal softening and melting, have been observed.
