Dy₂Ni₇Sn₃: a new member of the CaCu₅ family of inter­metallics

Single crystals of didysprosium hepta­nickel tritin were synthesized from the constituent elements by arc-melting. Two of the five Ni atoms are at general sites and all other atoms are at sites with either twofold or m symmetry. The structure contains `DyNi<sub>5</sub>Sn' and `DyNi₂Sn₂' fragments and represents a new member of the CaCu₅ series of inter­metallics.

S1. Comment

Investigation of the Dy–Ni–Sn ternary system revealed the presence of a large number of Ni-enriched compounds (Romaka et al., 2007), including a new stannide with the composition Dy₁₈Ni₅₅Sn₂₇. After the structure of this new stannide had been solved and refined, the crystal chemistry analysis was carried out. Interatomic distances (Table 1) in the structure are in good agreement with the sum of the corresponding atomic radii. No shortening of the interatomic distances between Sn atoms caused by covalent bonding (inherent in compounds with high Sn content) was observed. As most ternary intermetallics are constructed from the fragments of the most stable binary compounds, the structure analysis of already known Ni-enriched stannides shows that all are derived from the DyNi₅ binary compound which crystallizes in the CaCu₅ structure type (Wernick & Geller, 1959). The crystal structure of Dy₂Ni₇Sn₃ (Fig. 1a) belongs to the CaCu₅ family and contains `DyNi<sub>5</sub>Sn' (denoted I) and `DyNi₂Sn₂' (denoted II) fragments (Fig. 1b). The `DyNi<sub>5</sub>Sn' fragment seems to be very similar to that in DyNi<sub>5</sub>Sn (Skolozdra et al., 1996), but with a different position of one inner Ni atom. In other respects, both fragments are similar. The `DyNi₂Sn₂' fragment is a hypothetical structure because of the absence of a compound with such a stoichiometry in the Dy–Ni–Sn system. However, this fragment resembles the deformed fragment in the YB₂C₂ structure (Bauer & Nowotny, 1971). Stacking of the `DyNi<sub>5</sub>Sn' and `DyNi₂Sn₂' fragments in the sequence I–II–I'–I–II–I' may produce the structure of Dy₂Ni₇Sn₃ (Fig. 1b). The main feature of this compound is the method of stacking of the `DyNi<sub>5</sub>Sn' and `DyNi₂Sn₂' fragments and the fact that there is no possibility of sequentially building fragment I directly from the previous one (I') because the shared sides of these fragments are shifted and stack along the Dy plane.

By analyzing the Ni-enriched DyNi₅Sn, Dy₂Ni₇Sn₃ and DyNi₃Sn₂ (Skolozdra et al., 1988) ternary stannides of the Dy–Ni–Sn system, it was found that all of them were derived from the binary DyNi₅ genetic prototype. Structure relations between these compounds are shown in Fig. 2. While advancing from binary DyNi₅ to ternary DyNi₅Sn, the coordination polyhedron of the Dy atom splits into two different polyhedra. One replicates that of the binary compound and the other is slightly deformed, but still very similar to that in the DyNi₅ compound. Passing through DyNi₅Sn to Dy₂Ni₇Sn₃, the polyhedra for the Dy atoms become deformed, but the motif of the DyNi₅ fragment can be easily recognized. The Dy polyhedra of the last stannide, DyNi₃Sn₂, are almost analogous to the initial Dy polyhedron in the DyNi₅ compound.

S2. Experimental

A sample with nominal Dy₁₈Ni₅₅Sn₂₇ composition was prepared by arc-melting the Dy (99.9 wt.%), Ni (99.99 wt.%) and Sn (99.999 wt.%) metals on a water-cooled copper hearth under a protective Ti-gettered argon atmosphere. The obtained alloy was annealed at 870 K for 720 h in an evacuated silica ampoule and finally quenched in cold water. A crystal of Dy₂Ni₇Sn₃ suitable for single-crystal X-ray diffraction analysis was extracted directly from the annealed sample. The chemical composition of the crystal was determined via EDX analysis on a Carl Zeiss DSM 962 equipped with a Link EDX system, giving 18.2 (1)% Dy, 55.5 (3)% Ni, and 26.3 (2)% Sn. These values are very close to the composition calculated from the structure refinement.

S3. Refinement

The structure solution and refinement were also performed in the noncentrosymmetric space group C2ce but were less satisfactory and resulted in larger R indices and atomic displacement parameters.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
