The thermal reaction Of Ru3(CO)12 with (+/-) 7-oxabicyclo[2.2.1]hept-5-en-2-one (+/-)-2, (+/-) 7-oxabicyclo[2.2.1]hept-5-en-2-endo-ol 21 and the corresponding benzoate 22 afforded the [Ru3H2(CO)9 (7-oxabicyclo[2.2.1]hept-5-yn-2-yl)] clusters 13, 19 and 20, ...
The ternary sulfide Ag7TaS6 displays high Ag-ion conductivity at ambient temperature, and the framework TaS6 and Ag ions can be respectively regarded as the host structure and guest ions. Two low-temperature phases, i.e. Ag7TaS6 II and Ag7TaS6 III, were fo ...
The equimolar reaction of t-BuP(NH2)2 and Et2AlH yields [t-Bu(H)P(NH)2AlEt2]2 I, a novel eight-membered heterocycle contg. an AlNP-backbone; the crystal structure of which was detd. [on SciFinder (R)] ...
At -20 degrees C, SO2 undergoes homocheletropic addition with 7,7-dimethyl[2.2.1]hericene (18) to give (1R,5S)-6,10-dimethylidene-8-isopropylidene-3-thiatetracyclo[5.2.1.0(1,5 ).0(5,9)]decane 3,3-dioxide (21). This 3,3-dioxide (21). This sulfolane Is isome ...
The reactions of [Fe2(CO)9] with 2-exo,3-exo-bis(chloromethyl)-5,6-di(methylidene)-7-oxabicyclo[2.2.1]hep tane (5) and with 5,6-di(methylidene)-7-oxabicyclo[2.2.1]heptane-2-exo,3-exo-dimethyl bis(methanesulfonate) (6) afforded, together with the correspond ...
The metathesis reaction of TeBr4 and AgSb(OTeF5)6 in SO2 led to [TeBr3][Sb(OTeF5)6] and AgBr, and that of 2AgSb(OTeF5)6 with 7Te:TeBr4 led to [Te4][Sb(OTeF5)6]2. The crystal structure of [Cl3Te-F-TeCl3][Sb(OTeF5)6] is reported, prepd. from Te, TeBr4 and Ag ...
GalnSe(2) single crystals have been grown and characterized by experimental techniques such as high-resolution transmission electron microscopy, x-ray diffraction, x-ray photoelectron spectroscopy and optical and electrical measurements. The samples were p ...
The crystal structure of the new synthetic compound Ba-5[B20O33(OH)(4)] . H2O was established by the methods of X-ray diffraction (a Stoe IPDS diffractometer, lambda MoKalpha, 1860 independent reflections, anisotropic refinement, R = 1.95%, localization of ...
Norbornene and norbornadiene insert across the exo-face of their C=C bond into the Pd-acyl bond of [(OC)(3)Fe{mu-Si(OMe)(2)(OMe)}(mu-dppm)Pd{C(=O)Me}] and (1a) (dppm = Ph2PCH2PPh2) to afford the heterodinuclear complexes [(OC)(3){(MeO)(3)Si}Fe(mu-dppm)Pd{C ...
Molecular-geometry calculations in the superspace framework of incommensurate structure analysis are presented in detail. In particular, a method is described for attaching atoms to groups of others without the necessity of introducing further modulation f ...
