Redetermination of tetra­kis(trimethyl­stann­yl)germane

Redetermination of the structure of the title compound, [Ge(SnMe(3))(4)] or [GeSn(4)(CH(3))(12)], previously refined from powder diffraction data only [Dinnebier, Bernatowicz, Helluy, Sebald, Wunschel, Fitch & van Smaalen et al. (2002 ▶). Acta Cryst. B58, 52-61], confirms that four bulky trimethyl-stannyl ligands surround the central Ge atom (site symmetry 1) in a tetra-hedral coordination.

Tetrakis(sulfurdiimido)silane, -germane and -stannane

Z. Naturforsch. 53 b, 573-580 (1998); received March 30, 1998 Silicon, Germanium, Tin, Sulfur Diimides, Heterocycles, NMR Data Two tetrakis(sulfurdiimido)silanes [Si(NSNR)4 (R = rBu la, SiMe3 lb)], two germanes [Ge(NSNR)4 (R = rBu 2a, SiMe3 2b)] and one stannane [Sn(NSN?Bu)4Sn 3a] were prepared and characterised by 'H, l3C, i5N, 29Si and ll9Sn NMR spectroscopy in solution, and 3a was also studi...

Superconducting high pressure phase of germane.

High-pressure structures of germane (GeH4) are explored through ab initio evolutionary methodology to reveal a metallic monoclinic structure of C2/c (4 molecules/cell). The C2/c structure consists of layerlike motifs containing novel "H2" units. Enthalpy calculations suggest a remarkably wide decomposition (Ge+H2) pressure range of 0-196 GPa, above which C2/c structure is stable. Perturbative l...
