The compound W{sub 2}(H){sub 2}(O{sup i}Pr){sub 4}({eta}{sup 2}-dmpe){sub 2} reacts in hydrocarbon solutions with CO, CO{sub 2}, and H{sub 2}O to give ({sup i}PrO){sub 4}WW({eta}{sup 2}-dmpe){sub 2}(CO), 1, ({eta}{sup 1}-O{sub 2}CH)({sup i}PrO){sub 4}WW({eta}{sup 2}-dmpe){sub 2}H, 2, and [H({eta}{sup 2}-dmpe){sub 2}WWO{sub 2}]{sub 2}({mu}-O), 3, respectively. Compound 1 reacts with H{sub 2}O in hydrocarbon solvents to give W{sub 2}(O){sub 4}({mu}-O)[W({eta}{sup 2}-dmpe){sub 2}(CO)]{sub 2}, 4. The compounds 1--4 contain unsupported W-W bonds between metal atoms in greatly different oxidation states. The new compounds have been characterized by NMR and infrared spectroscopy, and compounds 1 and 4, by single-crystal X-ray studies.
