|Section7= }} ''trans''-Bis(dinitrogen)bis()molybdenum(0) is a coordination complex with the formula Mo(N2)2(dppe)2. It is a relatively air stable yellow-orange solid. It is notable as being the first dinitrogen containing complex of molybdenum.〔 ==Structure== Mo(N2)2(dppe)2 is an octahedral complex with idealized D4h point group symmetry. The dinitrogen ligands are mutually trans across the metal center. The Mo-N bond has a length of 2.01Å, and the N-N bond has a length of 1.10Å.〔Uchida, T; Uchida, Y; Hidai, M; Kodama, T. The Crystal and Molecular Structure of trans-Bis(dinitrogen)bis()molybdenum(0). Bull. Chem. Soc. Jpn. 1971, 44, 2883. 〕 This length is close to the free nitrogen bond length, but coordination to the metal weakens the N-N bond making it susceptible to electrophilic attack.〔Hidai, M; Yasuchi, M.
