The oxidation of reduced chlorides (MCl2) or chloride-hydrides (MClHx) of the lanthanides with sulfur (700-850°C, 7 d, sealed tantalum capsules or evacuated silica vessels) usually results in the formation of the sesquisulfides ...

The reaction of [MoO2((CH3)HN-O)2] and N-methylhydroxylammoniumchloride in an aqueous suspension with CS2 yields red crystals of the analytical composition MOC4H14N3O4S2. The crystal structure has been determined by single ...

NdSe1,9 has been prepared as grey, strongly reflecting platelets by reaction of elemental neodymium with selenium in the ratio 1 :2 and subsequent chemical vapour phase transport with iodine. It crystallizes in the tetragonal ...

Pr(CH3COO)3· 1.5 H2O crystallizes with the triclinic system, P̄1̄ (no. 2), Z = 4, a = 844.2(4), b = 1009.8(5), c = 1340.1(7) pm, α = 87.10(5), β = 76.25(6), y = 75.65(2)°, Vm = 161.9(1) cm3/mol, R = 0.049, Rw = 0.035. The ...

The syntheses of new compounds of the general formula A4[Nb6Cl18] (A = Ga, In, Tl) and A4[Ta6Cl18] (A = In, Tl) are reported. The indexing of their X-ray powder patterns was performed isotypically with K4Nb6Cl18]- A ...

The crystal structure of the acetic acid adduct of the so far unknown samarium(III) acetate dihydrate was determined from single-crystal four-circle diffractometer data. It has the composition [Sm (CH3COO)3(H2O)2] CH3COOH ...

The new compounds A4[Nb6Cl12(N3)6](H2O)2 (A = Rb, Cs) were synthesized from In4[Nb6Cl12Cl6] by substituting six terminal Cl ligands and the In+ ions in methanolic solution. An X-ray structure refinement was performed on ...

In this synthesis paper, the current state of research regarding teaching quality is discussed comparing science education, physical education, and history education, by referring to research on teaching in general. ...

The vinylogous Mukaiyama aldol reaction (VMAR) allows efficient access to larger segments for complex natural product synthesis, primarily polyketides, through the construction of vicinal hydroxyl and methyl groups as well ...
