摘要：
Aluminium hydrogen phosphite, Al2(HPO3)3, and gallium hydrogen phosphite, Ga2(HPO3)3, were prepared hydrothermally in Teflon-lined steel autoclaves at 473 K. The compounds are isostructural with Fe2(HPO3)3. The structures consist of very distorted MO6 octahedra which share faces to form a dimeric M2O9 unit. These dimers are interlinked by the phosphite groups, which link three different dimers into a three-dimensional arrangement having small proton-lined channels running parallel to the c axis.
