Abstract
In the crystal structure of the title compound, [Mn(C5H7O2)2(C12H8N2)], the Mn(2+) cation is coordinated by one bidentate 1,10-phenanthroline ligand and two acetyl-acetonate anions within a slightly distorted N2O4 octa-hedron. The asymmetric unit consists of one Mn(2+) cation situated on a twofold rotation axis, one half of a 1,10-phenanthroline ligand and one acetyl-acetonate anion. In comparison with the previous determination based on visually estimated intensities recorded on precession photographs, the current redetermination with image-plate data reveals bond lengths and angles with much higher precision.
