Abstract: The crystal structure of the title compound, (C3H12N2)- [V3O3(OH)2(PO4)2] 2H2O, has been reported by Soghomonian et al. [Chem. Mater. (1993), 5, 1690±1691]. We present here a redetermination of greatly improved precision and at a low temperature of 180 (2) K. The H atoms connected to oxygen have been successfully located and the coordination environments of the two crystallographically independent vanadium centres have been properly elucidated. Large channels, running along the a direction, contain water molecules and 1,3-diammoniopropane cations that are strongly hydrogen bonded to the anionic framework through N+ÐH O and OÐH O interactions. One vanadyl (V O) bond and the central ±CH2± group of 1,3-diammoniopropane are located on a mirror plane.
