Reaction of FeH2(η2-H2)(PEtPh2)3 (1) or W(η2-H2)(CO)3(PR3)2 (PR3 = P(C6H11)3 (2a), P(i-Pr)3 (2a), P(C5H9)3 (2c), P(i-Pr)(C6H11)2 (2d)) with 1/4[CuO-t-Bu]4 or 1/2[Cu(O-t-Bu)(PR3)]2 (PR3 = PPh3, P(C6H11)3, or PPh2Et) result in deprotonation and concomitant elimination of HO-t-Bu. Characterization and reactivity studies of the bimetallic products (PEtPh2)3Fe(μ-H)3Cu(PEtPh2) (3) and (PR3)2(CO)3W(μ-H)Cu(PR3) (PR3 = P(C6H11)3 (4a), P(i-Pr)3 (4b), and P(C5H11)3 (4c)) are described, including an X-ray crystallographic study of 3, The latter complex consists of a facial P3FeH3 moiety, bridged by three hydrides to a Cu-P fragment with an Fe-Cu of 2.319 (1) A?, Crystal data for 3 (233°K): a = 10.872 (2) A?, b - 18.512 (4) A?, c = 12,647 (3) A?, β= 94.10 (3)°, and Z = 2 in P21.
