Ba analogues of hewettite (CaV 6 O 16 β’ 9H 2 O) were synthesized by the hydrothermal methods. The compounds exhibit two phases formulated by BaV 6 O 16 β’ nH 2 O and Ba 1Ψx V 6 O 16 β’ nH 2 O (x+0.2, n+3), and the structure of BaV 6 O 16 β’ nH 2 O has been determined from a single crystal study.

A new layered vanadium oxide [H 3 N(CH 2 ) 4 NH 3 ](V 6 O 14 ) was synthesized hydrothermally under autogenous pressure at 1801C for 48 h from a mixture of H 2 N(CH 2 ) 4 NH 2 and V 2 O 5 in aqueous solution. Its structure was determined from singlecrystal X-ray diffraction at room temperature with
4Ψ , and As 5Ψ , but none of them crystallize in space group Pn2n. In the K/V/P/N(C 2 H 5 ) 3 / H 2 O system, three different K phases were found: K 0.5 VOPO 4 β’ 1.5H 2 O, KVOPO 4 , and K-FVP-1 (Frankfurt vanadium phosphate, one, or for short, FVP-1). The microporous K-FVP-1 compound was synthesize
