Dj. Xu et al., SYNTHESIS AND CRYSTAL-STRUCTURE OF BIS(ACETYLACETONATO) (ISONICOTINATO) MONOAQUAMANGANESE(III) DIHYDRATE, Polyhedron, 16(1), 1997, pp. 71-73
The title complex was synthesized by reaction of sodium isonicotinate
with manganese(III) acetylacetonate. The single crystal structure of t
he complex was determined by X-ray diffraction. Around the Mn-III atom
the octahedral coordination polyhedron is tetragonally elongated. An
isonicotinate anion coordinates to the Mn-III atom through the pyridin
e nitrogen atom in the axial direction with a Mn-N bond of 2.293(3) An
gstrom, while two acetylacetonate anions chelate to Mn-III in the equa
torial plane with average Mn-O length of 1.91 alpha. Copyright (C) 199
