DMAP-Induced Gallium Phosphites with Different Dimensionality

Abstract

Three novel gallium phosphites, Ga-3, Ga-2, and Ga-1, have been hydrothermally synthesized via the commercial 4-dimethylaminopyridine (DMAP) reagent serving as a template in Ga-3 and Ga-1 and a ligand in Ga-2. These main-group-metal phosphites present different topology from the first 3D framework containing extra-large 14ring (14R) channel (Ga-3) and then the second 2D organic−inorganic hybrid layer (Ga-2) to the first 1D gallium phosphite chain (Ga-1). The structure detail of the three compounds, examined by single-crystal X-ray diffraction (SXRD), is discussed to elucidate the topology difference.
