The Crystal Structure of NaM2IV(PO4)3; MeIV = Ge, Ti, Zr.

Single crystal growth of CaMg2(SO4)3 via solid‐ / gas‐phase reactions and its Nasicon‐related crystal structure

“…Another resemblance between both structures concerns the comparatively large temperature factors of the metal atoms that are located at the sites with 3 symmetry, viz. Ca (see table 2) and Na [14], respectively. In case of the NaZr 2 (PO 4 ) 3 structure, this behaviour is correlated with the high Na + -cation conductor properties [15,16].…”

“…Comparison of the crystal structure of CaMg 2 (SO 4 ) 3 with that of the isoformular (both compounds have the general formula AB 2 (CX 4 ) 3 ) NaZr 2 (PO 4 ) 3 (Nasicon) reveals a topological relationship. The unit cell of the NaZr 2 (PO 4 ) 3 structure (Z = 6, R3c, a' ≈ 8.81, c' ≈ 22.75 Å) [14] is tripled with a' ≈ a and c' ≈ 3c in respect to the unit cell of CaMg 2 (SO 4 ) 3 (note that there is no direct group-subgroup relation between space groups R3c and P6 3 /m), and the Ca, Mg and S atoms are replaced by Na, Zr and P, respectively.

Li1.14Nb0.93Sc0.67Cr0.40(PO4)3

“…Like the Nasicon structure (Hagrnan & Kierkegaard, 1968), the basic unit includes two MO6 octahedra linked by three PO4 tetrahedra (Fig. 1).…”

The D2h Distortion around the Cu2+ Center in Cu0.5Zr2(PO4)3 Single Crystals

“…Cu 0.5 Zr 2 (PO 4 ) 3 crystals belong to the Nasicon-type family with a three-dimensional network built of PO 4 tetrahedra sharing corners with ZrO 6 octahedra [1]. The three-dimensional network can be considered as being made of infinite ribbons linked by PO 4 tetrahedra.…”
