Popis:	The X-ray investigation of the title compounds has shown that in CH 3 COC 5 H 4 Mn(CO) 3 the orientation of CO groups with respect to the cyclopentadienyl ring is almost the same as in the unsubstituted manganese compound whereas in CH 3 COC 5 H 4 Re(CO) 3 the orientation is different to that in C 5 H 5 Re(CO) 3 , so that the molecule as a whole becomes less symmetrical. Unsubstituted cyclopentadienyl-manganese and -rhenium tricarbonyls are isostructural and entirely analogous; that the two acetyl derivatives are not isostructural is possibly caused by conformational differences. Both molecules have the “piano stool” configuration with the CH 3 CO group almost coplanar with the cyclopentadienyl ring plane. Interatomic distances and bond angles in these molecules are typical for this type of compound.
