Tris(bipyridine)Metal(II)-Templated Assemblies of 3D Alkali-Ruthenium Oxalate Coordination Frameworks: Crystal Structures, Characterization and Photocatalytic Activity in Water Reduction.

ABSTRACT: A series of 3D oxalate-bridged ruthenium-based coordination polymers with the formula of {[ZII(bpy)₃][MIRu(C₂O₄)₃]}n (ZII = Zn2+ (1), Cu2+ (3, 4), Ru2+ (5, 6), Os2+ (7, 8); MI = Li⁺, Na⁺; bpy = 2,2'-bipyridine) and {[ZnII(bpy)₃](H₂O)[LiRu(C₂O₄)₃]}n (2) has been synthesized at room temperature through a self-assembly reaction in aqueous media and characterized by single-crystal and powder X-ray diffraction, elemental analysis, infrared and diffuse reflectance UV⁻Vis spectroscopy and thermogravimetric analysis. The crystal structures of all compounds comprise chiral 3D honeycomb-like polymeric nets of the srs-type, which possess triangular anionic cages where [ZII(bpy)₃]2+ cationic templates are selectively embedded. Structural analysis reveals that the electronic configuration of the cation
