Description
Crystal structure and IR data for Tris((4-(ethoxycarbonyl)-1-phenyl-1H-pyrazol-5-yl)oxy)iron (46): FeCl3•6H2O (79.0 mg, 0.293 mmol, 1.00 equiv) was added with stirring to pyrazolone 6 (204 mg, 0.878 mmol, 3.00 equiv) and NaOAc (72.0 mg, 0.878 mmol, 3.00 equiv) in EtOH (6.0 mL) at 79 °C. The mixture was heated at reflux for 17 h, after which H2O was added (20 mL), the mixture was cooled to room temperature, and the precipitate was collected by filtration, washed with H2O (3 x 10 mL) and dried in vacuo. Fe-pyrazolone complex 46 (182 mg, 0.243 mmol, 83%) was obtained as a purple-red solid. Crystals suitable for X-ray crystallography were obtained by slow evaporation from an EtOH solution of complex 46. IR (Diamond-ATR, neat) νmax (cm-1) = 1606, 1593, 1580, 1527, 1498, 1471, 1457, 1429, 1387, 1357, 1323, 1256, 1116, 1083, 1002, 951, 779, 753, 687, 632. m.p.: 158 – 160 °C (EtOH). Anal. Calcd for C36H33FeN6O9: C, 57.69; H, 4.44; N, 11.21. Found: C, 57.74; H, 4.45; N, 10.44.
