The title compound was prepared by reaction of PhCH2Mn(CO)5 with 3'-acetoxyacetophenone in refluxing heptane, under the usual conditions (Main and Nicholson, 1994). The structure was determined to confirm that cyclometallation had occurred at the sterically crowded 2'-position, rather than the alternative 6'-position, and to detect any residual interactions with the adjacent acetoxy group which might have directed this preference.
All H-atoms were located as the highest peaks in a penultimate difference map and were refined with isotropic temperature factors.
(2-Acetyl-κO1-6-acetoxyphenyl- κC1)tetracarbonylmanganese(I) is formed by orthomanganation of 3'-acetoxyacetophenone at the sterically crowded ortho site. The atoms of the phenyl and the cyclometallated rings are coplanar to within <0.018 Å, and there are no significant intramolecular interactions between the Mn(CO)4 group and the adjacent acetoxy one. The Mn1—C12 distance trans to O1 (1.8046 (18) Å) is shorter than the Mn1—C11 distance trans to C1 (1.8367 (19) Å), while the two Mn—CO distances trans to each other are the longest (av. 1.857 (2) Å). The Mn1—C1 distance is significantly shorter than the Mn1—O1 distance (2.0445 (15) and 2.0548 (11) Å respectively) contrary to the trend expected purely on covalent radii. These conform to the pattern found for other orthomanganated arenes (Main and Nicholson, 1994).
The preparations and structures of related orthomanganated aryl ketones have been reviewed (Main & Nicholson, 1994). Preference in cyclometallation reactions for the more sterically crowded isomer for other 3'-substituted acetophenones has been observed (Cooney et al., 1988, 2001; Liebeskind et al., 1989).

(2-Acetyl-κO1-6-acetoxyphenyl- κC1)tetracarbonylmanganese(I) is formed by orthomanganation of 3'-acetoxyacetophenone at the sterically crowded ortho site. The atoms of the phenyl and the cyclometallated rings are coplanar to within <0.018 Å, and there are no significant intramolecular interactions between the Mn(CO)4 group and the adjacent acetoxy one. The Mn1—C12 distance trans to O1 (1.8046 (18) Å) is shorter than the Mn1—C11 distance trans to C1 (1.8367 (19) Å), while the two Mn—CO distances trans to each other are the longest (av. 1.857 (2) Å). The Mn1—C1 distance is significantly shorter than the Mn1—O1 distance (2.0445 (15) and 2.0548 (11) Å respectively) contrary to the trend expected purely on covalent radii. These conform to the pattern found for other orthomanganated arenes (Main and Nicholson, 1994).
