The new compounds WH6(PMe3)3, ReH7(PMe3)2, ReH7(PMe3)2·PhNH2, and Re2H8(PMe3)4 have been synthesised. Improved syntheses of MH4(PMe3)4(M = MO or W) are also described. The complex WH6(PMe3)3 reacts with carbon dioxide under pressure to yield the fluxional molecule [graphic omitted])(O2CH)(PMe3)3 with uni- and bi-dentate formate groups. The compounds have been characterised by infrared and nuclear magnetic
