syntheses and structures of a series of very low coordinate Barium Compounds ba n sime3 2 2 thf 2 ba n sime3 2 2 thf 2 and ba n sime3 2 2 2
Inorganic Chemistry, 1991Co-Authors: Brian A Vaartstra, John C Huffman, William E Streib, Kenneth G CaultonAbstract:Barium hexamethyldisilazide tetrahydrofuranate, Ba(N(SiMe{sub 3}){sub 2}){sub 2}(THF){sub 2} (1), is synthesized from Barium granules and 1,1,1,3,3,3-hexamethyldisiliazane at 25{degree}C in THF. Gaseous ammonia is a necessary catalyst. In the solid state, the compound is a monomer containing a tetrahedral four-coordinate Barium center. One of the coordinated THF molecules is removed from 1 by stripping a toluene solution of 1 to dryness in vacuo, yielding (Ba(N(SiMe{sub 3}){sub 2}){sub 2}(THF)){sub 2} (2). In the solid state, 2 is a dimer containing two bridging and two terminal hexamethyldisilamido groups. The four-coordinate, tetrahedral geometry at each Barium is completed by terminal THF molecules. The solvent-free compound (Ba(N(SiMe{sub 3}){sub 2}){sub 2}){sub 2} (3) is obtained by sublimation of 1. This compound is a dimer in the solid state, with three-coordinate Barium centers. Crystal data are reported for all these Compounds 14 refs., 3 figs., 9 tabs.

molecular copper Barium Compounds syntheses crystal structures and magnetic properties of two sandwich copper Barium complexes bacu4 bdmap 4 pyo 4 o2ccf3 2 0 5thf and bacu4 deae 4 pyo 4 o2ccf3 2 bdmap 1 3 bis dimethylamino 2 propanolato pyo deprotona
Inorganic Chemistry, 1993Co-Authors: Suning Wang, Steven J Trepanier, Michael J WagnerAbstract:Two pentanuclear copper-Barium complexes have been synthesized by the reactions of Cu(OPCH 3 ) 2 with Ba(O 2 CCF 3 ) 2 , 2-hydroxypyridine, and 1,3-bis(dimethylamino)-2-propanol (bdmapH) or 2-(diethylamino)ethanol (deaeH). Both Compounds were characterized structurally. The Barium ion is sandwiched between two dicopper anions, [Cu 2 L 2 (PyO) 2 (O 2 CCF 3 )] - (L=bdmap or deae) and coordinated by eight oxygen atoms.
