Four
two-dimensional fully reduced polyoxovanadates, namely, [Cd(DAP)2]4[HVIII3VIV18P6O60(DAP)3(HOCH2CH2OH)]·10H2O (1),
[Cd(DAP)2]4[HVIII3VIV18P6O60(DAP)3(CH3OH)]·11H2O (2), [Cd(DAP)2]4[HVIII3VIV18P6O60(DAP)3(CH3CH2OH)]·4H2O (3) and CoIII(DAP)3[CoII(DAP)2]3[VIII3VIV18P6O60(DAP)3(HOCH2CH2OH)]·14H2O (4)
were synthesized by virtue of the reducing power of alkylamine in
hydrothermal conditions. Single-crystal X-ray structural
analysis, magnetic measurement, IR spectroscopy, elemental analysis,
and thermogravimetric measurements were performed to analyze the structures
and properties of these four compounds. Structural analysis indicates
that the four compounds contain the same huge low-valent vanadium
oxide anion cages [VIII3VIV18P6O60(DAP)3]9–, and the cages can catch different guest molecules. Four cages are
linked by Co or Cd atoms to form a four-membered ring, while adjacent
four-membered rings are connected to each other by sharing edges to
make an inorganic–organic hybrid layer. The magnetic susceptibility
measurements of four compounds indicate ferrimagnetic interactions
between vanadium ions.
