Chromium nitride synthesis

As discussed above, the ligands that have been typically utilized for the preparation of chromium nitrides are multidentate. Consequently, ligand exchange reactions of such complexes are difficult and rare. Wieghardt and co-workers have reported such a process, however, for the synthesis of a nitrido chromium cyanide complex 43 (Eq. (13)) [18]. Thus, treatment of CrN(salen) 42 with excess sodium cyanide and tetramethyl ammonium chloride results in the formation of a six-coordinate penta-cyano chromium nitride [21].

Chromium Nitrides. Crystalline cubic phase CrN was obtained by the chemical reaction of CrCls, LisN, and NH4CI at high pressure (49) kbar) and instantaneous heat treatment like MoN synthesis (31). In another chemical procedure, mesoporous CrN was made by a hard template of SBA-15 (62). The precursor Cr03 was put into the SBA-15 pores, then the calcination was performed for the formation of Cr203/SBA-15 under 873 K. Subsequent ammonolysis at 1223 K produced CrN/SBA-15. The silica template in CrN/SBA-15 was removed by NaOH treatment to obtain mesoporous CrN with a high surface area of 78 m /g.
