Molybdenum bis(imido) bis(thiolato) complexes of the type Mo(N^tBu)₂(SR)₂ (R = ^tBu (1), ⁱPr (2)) were synthesized and evaluated as precursors for the aerosol-assisted chemical vapor deposition (AACVD) of nitrogen-doped molybdenum disulfide. Decomposition of the precursors was examined using mass spectrometry and thermolysis experiments, and the predominant pathways were those that involved proton transfer from a methyl group on a thiolato ligand. Thermal behavior, volatility, and enthalpies of sublimation were analyzed using TGA. Comparative studies of the nitrogen-doped MoS₂ (N-MoS₂) grown from Mo(N^tBu)₂(S^tBu)₂ to that of pristine MoS₂ grown from Mo(S^tBu)₄ were carried out. The material was characterized as MoS₂ with nitrogen doping by the presence of the 2H-MoS₂¹E_2g and A_1g Raman vibrational modes. The GIXRD diffraction patterns of the N-MoS₂ samples were indexed to 2H-MoS₂, and evidence of nitrogen doping was confirmed with the presence of Mo–N bonding by XPS and with EDS mapping. The N-MoS₂ deposits displayed a nanosphere morphology which contrasted with vertical nanosheets for undoped MoS₂.
