Abstract
The title compound, (C8H20N)[Mn2(C6H5O)3(CO)6], was synthesized from [Mn(CO)3(CH3CN)3]BF4 and (C8H20N)(OC6H5). The binuclear anion exhibits a pseudo-threefold symmetry and contains two six-coordinate Mn atoms. Each metal atom is coordinated by three facially oriented CO ligands and three doubly-bridging phenolate ligands. The average O—Mn—O bond angle is 74.9 (7)° in the Mn2O3 metal–phenolate dimeric core, yielding a distorted octahedron for each metal.

The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2
