We have synthesized a new 16-electron precursor [Mn(CO)(dppe){sub 2}]BAr`{sub 4} (1) capable of binding small molecules (dppe = Ph{sub 2}PC{sub 2}H{sub 4}PPh{sub 2}; BAr`{sub 4} = B[C{sub 6}H{sub 3}(3,5-CF{sub 3}){sub 2}]{sub 4}). This species has yielded the first well-characterized cationic manganese-H{sub 2} complex, [Mn(H{sub 2})(CO)(dppe){sub 2}]BAr`{sub 4}. The complexes MnH{sub 3}(R{sub 2}PC{sub 2}H{sub 4}PR{sub 2}){sub 2} [R = Me (dmpe), Et (depe)] were proposed to contain H{sub 2} ligands, and CpMn(CO){sub 2}(H{sub 2}) was recently isolated. We also report that N{sub 2} reaction with 1 gives an extremely labile N{sub 2} complex characterized by {sup 15}NMR. 18 refs., 1 fig.
