- ItemTetracarbonyl[bis(diphenylphosphanyl)-tetramethyldisiloxane- κ 2 P,P′]chromium(0)(Chester : International Union of Crystallography, 2012) Peulecke, N.; Müller, B.H.; Spannenberg, A.; Rosenthal, U.The title compound, [Cr(C 28H 32OP 2Si 2)(CO) 4], was obtained by the ligand-exchange reaction of Cr(CO) 6 with (Ph 2PSiMe 2) 2O in refluxing toluene. The CrC 4P 2 coordination geometry is distorted octa-hedral, with a P - Cr - P bite angle of 99.22 (4)°.
- ItemTris(tetrahydrofuran-kO)tris[tris(thio-phen-2-yl)methanolato-kO]terbium(III)tetrahydrofuran monosolvate(Chester : International Union of Crystallography, 2011) Veith, Michael; Belot, Celine; Huch, VolkerIn the mononuclear title compound, [Tb(C13H9OS3)3(C4H8O)3]·C4H8O, the lanthanide cation is located on a threefold rotation axis and is surrounded by electron-rich ligands in an approximately octahedral geometry. One of the thienyl groups and the bound THF are disordered with 0.5:0.5 occupancy. The free THF is disordered around the threefold axis.
