1H NMR (400 MHz) spectra were recorded on a JEOL
ECS400. Chemical shifts were reported in δ ppm, referenced to an
internal tetramethylsilane standard for 1H NMR spectroscopy.
Infrared spectra were measured using a Thermo Nicolet AVATAR 320 FT-IR
spectrometer. FAB-MS spectra were recorded on a JEOL JMS-700TZ. Elemental
analyses were performed on a J-Science Lab Micro Corder JM 10 and an Exeter
Analytical CE440. In addition, the ratio of F to Eu was measured using Energy
Dispersive X-ray Fluorescence Spectrometer EDX-8000 with (reference material:
Eu(hfa)3(TPPO)2). XRD patterns were characterized by a
RIGAKU SmartLab X-ray diffractometer with Cu Kα radiation, a D/teX
Ultra detector, and a temperature control unit (Anton Paar, TCU-110).
Thermogravimetric Analysis was performed on a Seiko Instruments Inc. EXSTAR 6000
(TG-DTA 6300) at first heating rate of 10 °C
min−1 up to 100 °C,
cooling rate of 10 °C min−1up to 40 °C, and second heating rate of
1 °C min−1 up to
500 °C.
