Diisocyanoarene-linked pentacarbonylvanadate(I-) ions as building blocks in a supramolecular charge-transfer framework assembled through noncovalent π-π and contact ion interactions

Three synthetic routes to the unusual supramolecular complex ([Cp(2)Co](2)[{(OC)(5)V}(2)(μ-1,4-CNC(6)Me(4)NC)])(∞), which was crystallographically characterized, are presented. The dianion [{(OC)(5)V}(2)(μ-1,4-CNC(6)Me(4)NC)](2-) constitutes the first subvalent organometallics featuring a diisocyanoarene linker.     

Quenching of giant hysteresis effects in La(1-z)Y(z)Hx switchable mirrors

Hydrogen atoms adsorbed on TiO2(110)-(1x1) surfaces have been characterized by scanning tunneling microscopy (STM) combined with electron stimulated desorption (ESD) technique. Certain amounts of H atoms are unexpectedly found on the TiO2 surfaces annealed at 900 K. Two forms of adsorption were discriminated in STM images from the different sensitivity to ESD and tentatively assigned to hydroxyl-type (O-H) and hydride-type (Ti-H) species.
