KH is used to deprotonate ReH{sub 7}L{sub 2} (L = PMe{sub 2}Ph, PMePh{sub 2}, and PPh{sub 3}) and ReH{sub 5}P{sub 3} and WH{sub 6}P{sub 3} (P = PMe{sub 2}Ph) in THF, and the resulting anions are characterized by variable-temperature multinuclear NMR. The solid-state structure of K(THF){sub 2}ReH{sub 6}(PPh{sub 3}){sub 2} was determined by x-ray diffraction and revealed a centrosymmetric dimer connected by bridging hydrogen atoms. Crystallographic data (213 K): a = 10.987 (2), b = 27.134 (4), c = 14.030 (2) {angstrom}, {beta} = 96.609 (13){degree}; V = 4154.6 (11) {angstrom}{sup 3}, and Z = 2 in space group P2{sub 1}/n.
