The P and O atoms of the substituted trioxofluorophosphate and phosphite anions share the same positions while the P-F and P-H hydrido are almost parallel and oriented in the same direction. Two symmetry-independent anions and two of three symmetry-independent cations are situated on the crystallographic mirror planes. The ions are interconnected by N-H O hydrogen bonds of moderate strength. The title crystals were also characterized by FTIR and FT Raman and the second harmonic generation (SHG). The relative SHG efficiency considerably decreases from bis(guanidinium) trioxofluorophosphate to bis(guanidinium) phosphite for the fundamental 1064 nm laser line.
