Description
Crystal structure, NMR and IR data for Bis(ethanol) bis((4-(ethoxycarbonyl)-1H-pyrazol-5-yl)oxy)nickel (60): NiCl2•6H2O (96.0 mg, 0.384 mmol, 1.00 equiv) was added with stirring to pyrazolone 5 (120 mg, 0.769 mmol, 2.00 equiv) in EtOH (3.5 mL) at 79 °C. After 24 h at reflux, the mixture was cooled to room temperature, and the resultant precipitate was collected by filtration and dried in vacuo. Ni-pyrazolone complex 60 (110 mg, 0.239 mmol, 62%) was obtained as a green solid. Crystals suitable for X-ray crystallography were obtained by slow evaporation from an ethanolic pyridine solution of complex 60. IR (Diamond-ATR, neat) νmax (cm-1) = 3325, 1636, 1560, 1548, 1526, 1470, 1443, 1323, 1278, 1172, 1126, 1067, 933, 785. m.p.: 255 – 257 °C (EtOH). Anal. Calcd for C12H14N4O6Ni ∙ 1.1 NiO ∙ 0.5 EtOH: C, 32.93; H, 3.61; N, 11.82. Found: C, 32.41; H, 3.68; N, 11.12.
