Abstract
Solid-state thermal reactions of trans-[Mo(N2)(L)(dppe)2] were investigated under quasi-isothermal and quasi-isobaric conditions (Q conditions) and under open dynamic conditions (D conditions). (L is a π-accepting ligand selected from CO, N2 and C6H5CN, and dppe stands for 1,2-bis(diphenylphosphino)ethane.) The results show that trans-[Mo(N2)(CO)-(dppe)2]·12C6H6 evolves dinitrogen plus 12C6H6 at 100–170 ° C to produce a five-coordinated intermediate [Mo(CO)(dppe)2], which then undergoes disproportionation to produce cis-[Mo(CO)2(dppe)2] and unknown materials. When L is N2 or C6H5CN, both the complexes evolve dinitrogen, but they undergo complicated decomposition with no formation of a stable five-coordinated intermediate. The stability of the five-coordinated intermediate [Mo(CO)-(dppe)2] is attributed to the greater π-accepting ability of CO compared with N2 and C6H5N.
