Investigation into the crystal structure of gallium-selenide nanowires
Gallium-selenide films grown by heteroepitaxy on silicon substrates exhibit two primary growth structures: layered GaSe and defected zinc-blende Ga2Se3. The latter is seen when growing on the (100) surface of silicon, and an emergent structure of nanowires is observed. My project for the ten week summer program at the University of Washington physics department was to investigate the nanowire s...
متن کاملCrystal structure of a samarium(III) complex of tripodal tris(((5-chlorosalicylidene)amino)ethyl)amine.
known to have a coordination number of seven. Nearly all of them have the basic formulation [Ln(bidentate)3(unidentate)]. On the contrary, structurally characterized examples of a heptadentate ligand coordinating one metal ion are rare. Tris(2-aminoethyl)amine (tren) condenses with salicylaldehyde or its substituted analogs in a 1:3 molar ratio to form Schiff-bases which are potentially tribasi...
متن کاملCrystal structure of a samarium(III) nitrate chain cross-linked by a bis-carbamoylmethylphosphine oxide ligand
In the title compound poly[aqua-bis-(μ-nitrato-κ(4) O,O':O,O'')tetra-kis-(nitrato-κ(2) O,O'){μ4-tetra-ethyl [(ethane-1,2-diyl)bis(aza-nedi-yl)bis-(2-oxo-ethane-2,1-di-yl)]di-phospho-nate-κ(2) O,O'}disamarium(III)], [Sm2(NO3)6(C14H30N2O8P2)(H2O)] n , a 12-coordinate Sm(III) and a nine-coordinate Sm(III) cation are alternately linked via shared bis-bidentate nitrate anions into a corrugated chain...
متن کاملSYNTHESIS AND CRYSTAL STRUCTURE OF [PPh ] [WOS (CUNCS) ]
The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...
متن کاملCrystal Structure of Nonaaquayttrium(III) Bromate at 100 K
The structure of the nonaaquayttrium (III) bromate, [Y(H2O)9](BrO3)3, at low temperature (100 K) has been studied by means of single-crystal X-ray diffraction. Crystallography shows a hexagonal unit cell, space group P63/mmc (No. 194) with Z = 2, a = b = 11.7104(11) Å, c = 6.6259(5) Å and V = 786.90(12) Å3 at 100 K. The hydra...
