Abstract: The title compound [N(CH3)4]4[H5PMo5V9O42] ·3.5H2Owas synthesized by hydrothermal method and its structure was determined with single crystal X-ray analysis. The cluster anion is a bicapped Keggin polyanion, two vanadium atoms are distributed at two capping metal atom positions. The crystal is monoclinic, space group C2/c with a=1.2848(4) nm, b=2.3664(4) nm, c=2.1136(4) nm, β= 90.69(2)°, V=6.425(4) nm 3, Z=4, Dc=2.07 g·cm-3, R=0.066, Rw=0.069, S=1.33, {(Δ/σ)max=}004, {(Δρ)max =}91 e·nm-3.
