Abstract

A novel synthetic route to amorphous C3N4 polymeric structures has been developed. This method involves thermal decomposition of novel molecular precursors such as C3N3X2N-(SnMe3)2 (X = F, Cl), via elimination of stable XSnMe3 species, to produce thin films or bulk materials of composition C3N4, the highest nitrogen content observed in C-N solids. These materials are primarily sp2 hybridized, as indicated by vibrational, solid-state NMR, and electron-energy-loss studies, and they are likely to be excellent precursors for the highpressure synthesis of tetrahedral C3N4, the structural analog of β-Si3N4. A crystal structure determination of C3N3F2N(SnMe3)2 reveals that the N(CN)3 framework of the molecule is planar, and all C-N bonds have virtually the same length.
