Tetraethyl-ammonium tri-μ-phenolato-bis[tricarbonylmanganate(I)]

Abstract

The title compound, (C 8H 20N)[Mn 2(C 6H 5O) 3(CO) 6], was synthesized from [Mn(CO) 3(CH 3CN) 3]BF 4 and (C 8H 20N)(OC 6H 5). 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 Mn 2O 3 metal-phenolate dimeric core, yielding a distorted octa-hedron for each metal.
