The C-N samples were synthesized at 500 degrees C from melamine and four kinds of pitch. At 50-100 mass % of pitch all samples were single phase nitrogen solid solutions in graphitic carbon. Maximal detected concentration of 22.4 mass % N correspond to solid solution with formula C100H26.8N26.3O3.1. According to infrared spectroscopy the N atoms chaotically substitute carbon. The electric resistivity of samples with 22.4 mass % N was 1.3-67 Omega*m, which is 100-1000 times lower than resistivity of corresponding graphitic carbon without doping (430-6700 Omega*m). The resistivity of graphitic C3N4 is about 10(11) Omega*m.
