✦ Synopsis
The hydrothermal synthesis and the structural determinations of two vanadium oxides interleaved by quinuclidinium cations are described; (NC 7 H 14 ) 4 [H 2 V 10 O 28 ] is an anhydrous diprotonated decavanadate (triclinic, P 1 (n°2), a = 9.701(1) A Ê , b = 10.839(1) A Ê , c = 12.7566(2) A Ê , α = 109.13(1)°, b = 112.09(1)°, c = 92.17(2)°) and (NC 7 H 14 )[V 4 O 10 ] a layered compound (orthorhombic, C mcm (n°63), a = 18.4461(5) A Ê , b = 6.6619(2) A Ê , c = 11.7967(2) A Ê ). Thermodiffractometry shows that the decavanadate irreversibly transforms at 230 °C into the layered compound without any amorphous intermediate state.
