The low-temperature form of K 3 Sm(PO 4 ) 2 crystallizes in the glaserite type. The Raman and infrared spectra have been investigated: they are consistent with the proposed space monoclinic system [a = 7.4347(5) A ห, b = 5.6270(5) A ห, c = 9.4919(5) A ห, ฮฒ = 90.870(6)ยฐ, Z = 2, space group P2 1 /m].
The crystal structure of a new apatite Ca 6 Sm 2 Na 2 (PO 4 ) 6 F 2 has been determined using 842 independent re6ections (R โซุโฌ 0.059, R w โซุโฌ 0.076). The unit cell constants are a โซุโฌ 9.3895(3) A > , c โซุโฌ 6.8950(4) A > with P6 3 /m space group. The structure contains disordered cations in both the
