“…To designate the endothermic peak, we calcined the as-prepared polycrystalline powder at 200–600 °C with interval XRD characterization in open and closed systems, respectively (Figure a). Notably, the Sn 3 B 8 O 15 phase is stable before 500 °C, and it is decomposed to SnO 2 at 600 °C, which confirms that the phase is stable in the air (<500 °C) similar to the reported Sn compounds. − , The same result is found in the closed system. Hence, the endothermic peak is the decomposition peak and Sn 3 B 8 O 15 melts incongruently.…”

Owing to the tendency to form the glass state in growing crystals in the ternary tin(II) borate system, hitherto, very few single crystals in ternary tin(II) borate were reported. In this paper, a single crystal of Sn3B8O15 was obtained via a high temperature solution method in a closed system. The structure features a flexible fundamental building block [B8O18]12– constructed by one [BO3]3– unit and one [B7O16]11– group that contains three hexatomic rings, which further connect to compose a two-dimensional 2 ∞[B8O15] layer structure. The connection mode and flexibility of the three hexatomic B-O rings were analyzed, verifying the structural diversity of the B-O configuration. Moreover, the synthesis, crystal structure, and various characterizations were comprehensively presented. Also, theoretical calculations were employed to discuss structure-property relationships, and we use the real-space atom-cutting techniques to explain the origin of the birefringence of Sn3B8O15.

“…The synthetic compound Ni 5 SnO 4 (BO 3 ) 2 crystallizes in the space group Pnam (No. 62), with a doubled c axis compared with the ludwigite unit cell (Bluhm & Mü ller-Buschbaum, 1989a). Doubling of the unit cell is a consequence of cation ordering in conjunction with the 5:1 ratio between divalent and tetravalent metal ions.…”

The crystal structures of malachite Cu(2)(OH)(2)CO(3) and rosasite (Cu,Zn)(2)(OH)(2)CO(3), though not isotypic, are closely related. A previously proposed approach explaining this relation via a common hypothetical parent structure is elaborated upon on the basis of group-subgroup considerations, leading to the conclusion that the aristotype of malachite and rosasite should crystallize in the space group Pbam (No. 55). An ICSD database search for actual representatives of this aristotype leads to the interesting observation that the structure type of ludwigite (Mg,Fe)(2)FeO(2)BO(3), which is adopted by several natural and synthetic oxide orthoborates M(3)O(2)BO(3), is closely related to the proposed malachite-rosasite aristotype and thus to the malachite-rosasite family of hydroxide carbonates M(2)(OH)(2)CO(3) in general. Relations within both structure families and their analogies are summarized in a joint simplified Bärnighausen tree.

“…In the crystal structure of the ludwigite-type M II 5 M IV B 2 O 10 , as well as Cu 5 SnB 2 O 10 , M IV atoms occupy mixed sites with a portion of M II atoms, and the mixed sites of M II and M IV atoms are statistically distributed along the c -axis (or the a -axis for Cu 5 SnB 2 O 10 ). The oxyborates of Ni 5 M IV B 2 O 10 (where M IV = Sn and Hf; orthorhombic, space group Pnma (No. 62), unit-cell parameters of a ≈ 9 Å, b ≈ 6 Å, and c ≈ 12 Å) have a type of the ludwigite-type superstructure.…”

Single crystals of magnesium tin oxyborate, Mg 5 SnB 2 O 10 (Mg 5 SnO 4 (BO 3 ) 2 ), were prepared at 1350°C in air, using B 2 O 3 as a flux. They were colorless and transparent with needlelike or columnar shapes. X-ray diffraction analysis of the single crystals revealed that Mg 5 SnB 2 O 10 crystallizes in the triclinic space group F1 (No. 2) with Z = 16, a = 6.1295 (8), b = 18.714(3), c = 24.719(3) Å , R = 90.021(5)°, β = 90.032(4)°, γ = 90.041(5)°, and V = 2835.4(7) Å 3 (R1 = 0.0168, wR2 = 0.0459, and S = 1.297 for all data). The crystal structure of Mg 5 SnB 2 O 10 is a ludwigite-type superstructure. Mg and Sn atoms are ordered and coordinated by six O atoms, and the edges of MO 6 (where M = Mg and Sn) octahedra are connected along the a-axis and form zigzag walls. B atoms are in the spaces surrounded by the walls and are coordinated by three O atoms. Polycrystals of titanium(IV)-doped solid solutions, Mg 5 Sn 1-x Ti x B 2 O 10 (0 < x e 0.50), were also prepared by solid state reaction at 1300°C in air. The refined unit cell volumes decreased with increasing titanium content (x), indicating partial substitution of Ti for Sn atoms. A broad blue emission with a peak wavelength of ∼430 nm was observed from the solid solutions under 265-nm ultraviolet excitation. A quantum efficiency of 0.81 was measured at room temperature for Mg 5 Sn 0.80 Ti 0.20 B 2 O 10 .
