the [M(CO)(3)](+) core (M = (99)Tc, Re) by formation of the complexes fac-[Mkappa(3)-H(mu-H)(2)B(tim(Me))}(CO)(3)] (M = (99)Tc (1), Re (2)), fac-[Rekappa(3)-H(mu-H)(2)B(tim(Bupip))}(CO)(3)] (3), and fac-[Rekappa(3)-H(mu-H)(2)B(bzt)}(CO)(3)] (4), respectively. The soft scorpionates are coordinated to the metal in unique (kappa(3)-H, H', S) fashion, as confirmed by X-ray crystallography of 1, 2, and
