摘要：

A new route to an alkoxohexavanadate species leads to the isolation of a bowl-type dodecavanadate without a guest molecule in the cavity. The ID tetravanadate, [V4O11](2-), is a good precursor for the alkoxohexavanadate, [V6O13(OCH3)(6)](2-), which is then utilized for the [V6 + V6] coupling reaction to form the dodecavanadate, [V12O42](4-), with a capped dichloromethane molecule at the cavity entrance. We also obtained structural information on a newly discovered octadecavanadate, [V18O46(NO3)](5-), in both the solid and solution states through extended X-ray absorption fine structure (EXAFS) studies. The existence of the chiral inorganic species in acetonitrile with double-stranded V8 chains was confirmed through EXAFS oscillations.
