Abstract
Intercalates of VOPO4 with several linear unsaturated alcohols (2-propen-1-ol, 2-buten-1-ol, 2-propyn-1-ol, 2-butyn-1-ol, 3-butyn-1-ol 2-pentyn-1-ol, 3-pentyn-1-ol, 4-pentyn-1-ol, 5-hexyn-1-ol, 2-octyn-1-ol, and 10-undecyn-1-ol) have been prepared and characterized by powder X-ray diffractometry, IR and Raman spectrometry, and thermogravimetry. The arrangement of the alcohol molecules with respect to the type and position of the multiple bonds in the carbon chain is proposed. Alcohols with terminal triple bonds form very stable intercalates. It is presumed that these alcohols are anchored to the host layers by donor-acceptor bonds between their oxygen atoms and the vanadium atoms of the host, and by H-bonding between the acetylenic hydrogen of the terminal carbon and the oxygen atoms of the host.
