Abstract
The design of molecular analogs, precursors to tungsten and molybdenum carbides is described. General design criteria for the synthesis of materials precursors are developed. Specific goals were to design nonvolatile, tractable precursors containing multiple metal-carbon bonds to enhance the formation of metal carbides upon pyrolysis. Pyrolysis of (C5H5)2W2(CO)4DMAD (DMAD = dimethyl acetylene dicarboxylate) at 750°C gives W2C under appropriate reaction conditions. Pyrolysis of Mo2(NMe2)6 at 800°C gives Mo2C rather than the expected MoN. A rationale for the latter result is presented.
