Abstract
Multiply bonded organometallic complexes Re-2(mu -Cl)(mu-eta (2)-HCCH)Cl-4( mu -dppm)(2) (2) and Re-2(mu -Cl)(mu -CCH2CH3)Cl-4(mu -dppm)(2) (3) are for med upon refluxing Re-2(mu -O2CCH3)Cl-4(mu -dppm)(2) (1) with HO2CC=CCO2H a nd CH3C=CCO2H, respectively; these reactions are believed to proceed via th e in situ formation of the corresponding metal alkynoates and the crystal s tructures of 2 and 3 show that the Re-Re distances of 2.6567(5) and 2.5277( 6) Angstrom are in accord with Re-Re bond orders of 1.5 and 2, respectively .
