Abstract

The title compounds (IV), (VI), (IX), and (XI) are prepared as shown in the scheme (yields not given) and their single crystal XRD data are reported.

Crystal structure of tetrakis[μ-3-carboxy-1-(1,2,4-triazol-4-yl)adamantane-κ2 N 1:N 2]tetrafluoridodi-μ2-oxido-dioxidodisilver(I)divanadium(V) tetrahydrate

“…Heterometallic hybrids incorporating a metal oxide/ oxofluoride matrix are of particular interest as they exhibit non-trivial magnetic, luminescent (Cui et al, 2012), optical and catalytic properties (Dolbecq et al, 2010). Among the broad range of inorganic anions, vanadium oxofluorides (VOFs) stand out for their large number of types and structural motifs from mono- (Aldous et al, 2007;Stephens et al, 2005) to polynuclear (Buchholz et al, 1988;Ninclaus et al, 1997) ones in the structure as discrete units or incorporated into coordination frameworks (Welk et al, 2007;Mahenthirarajah et al, 2008). The Ag I /VOF pair is a non-typical combination for classical coordination chemistry, but materials such as Ag 4 V 2 O 6 F 2 (Sorensen et al, 2005;Albrecht et al, 2009) and Ag 3 VO 2 F 4 (Chamberlain et al, 2010) are attractive electrochemically active phases for solid-state batteries.…”
