Description

Crystal structure, NMR and IR data for Bis(ethanol) bis((4-(ethoxycarbonyl)-1-phenyl-1H-pyrazol-5-yl)oxy)manganese (42): Mn(OAc)2 (67.0 mg, 0.388 mmol, 1.00 equiv) was added with stirring to pyrazolone 6 (180 mg, 0.775 mmol, 2.00 equiv) in EtOH (6.5 mL) at 79 °C. The mixture was heated at reflux for 4 h, cooled to room temperature, Et2O was added (15 mL), and the precipitate was collected by filtration and dried in vacuo. Mn-pyrazolone complex 42 (140 mg, 0.230 mmol, 59%) was obtained as a white solid. Crystals suitable for X-ray crystallography were obtained by slow evaporation from an EtOH solution of complex 42. IR (Diamond-ATR, neat) νmax (cm-1) = 1626, 1597, 1559, 1525, 1498, 1457, 1428, 1381, 1374, 1324, 1312, 1247, 1232, 1120, 1083, 952, 852, 780, 751, 687. m.p.: >230 °C (EtOH), (decomp.). Anal. Calcd for C24H22MnN4O6: C, 55.71; H, 4.29; N, 10.83. Found: C, 55.38; H, 4.29; N, 10.88.
