14. The WAXD (2θ = 5-40°) and SAXS (2θ = 0.5-5°) experiments were performed with a 12 kW rotating-anode X-ray generator (Rigaku RDA operated at 150 mA at 40 kV) at room temperature. The Cu Kα; X-ray source (λ = 1.54 Å) was monochromatized with a plate-like graphite monochrometer. The small-angle X-ray scattering (SAXS) intensity distribution was measured with a position sensitive proportional counter (PSPC).
15. It is notable that we have also isolated tris(DL-alaninato)yttrium(III) complex and confirmed that it is very hard to take a glassy state.
