The stannides Li 2 CuSn 2 and Li 2 AgSn 2 were synthesized by induction-melting (or in a muffle furnace) of the elements in sealed niobium ampoules. The new phases were characterized by powder Xray diffraction. The structures of both stannides were investigated by X-ray diffraction on single crystals: Li 2 AuSn 2 type, I4 1 /amd, a = 442.6(1), c = 1940.9(8) pm, wR2 = 0.0742, 310 F 2 values for Li 2 CuSn 2 and a = 456.33(9) c = 2018.2(6) pm, wR2 = 0.0626, 339 F 2 values for Li 2 AgSn 2 with 10 variables for each refinement. The transition metal (T) atoms have tetrahedral tin coordination. The TSn 4 tetrahedra are condensed via common corners forming layers that are further con-* Prof. Dr. R. Pöttgen

Lithium alloys of group IV elements such as silicon and germanium are attractive candidates for use as anodes in high-energy-density lithium-ion batteries. However, the poor capacity retention arising from volume swing during lithium cycling restricts their widespread application. Herein, we report high reversible capacity and superior rate capability from core-shell structure consisting of germanium nanorods embedded in multiwall carbon nanotubes. To understand how the core-shell structure helps to mitigate volume swings and buffer against mechanical instability, transmission electron microscopy, X-ray diffraction, and in situ (7)Li nuclear magnetic resonance were used to probe the structural rearrangements and phase evolution of various Li-Ge alloy phases during (de)alloying reactions with lithium. The results provide insights into amorphous-to-crystalline transition and lithium germanide alloy phase transformation, which are important reactions controlling performance in this system.

“…This shift is necessary to achieve reasonable lithium coordination. The Li-Li distances of 255-268 pm are similar to Li 4 Pt 3 Si (Dinges et al 2011). Figure 6 displays the crystal structures of LiZnSb (Schröder and Schuster 1975) and LiCu 0.93 As (Schönemann and Schuster 1977).…”

“…Keeping the electron-precise Zintl description (3Li + )RE 3+ (2Sb 3-) in mind, the shorter Li-Li distances are readily understandable. In lithium-rich intermetallic phases like Li 4 Pt 3 Si (Dinges et al 2011), even shorter Li-Li distances (244 pm) have been observed. The lanthanum atoms have almost ideal octahedral antimony coordination.…”

Lithium-transition metal (T)-pnictides (Pn = P, As, Sb, Bi) are an interesting class of materials with greatly differing crystal structures. The transition metal and pnictide atoms build up covalently bonded networks that leave cavities or channels for the lithium atoms. Depending on the bonding of lithium to the polyanionic network, one observes mobility of the lithium atoms. The crystal chemistry, chemical bonding, 7 Li solid-state NMR, and the electrochemical behavior of the pnictides are reviewed. The structural chemistry is compared with related tetrelides.
