Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, Computed Properties of C10H20O5.
Treatment of [U(Cp*)2Cl2] with Na 2dddt in thf afforded the “ate” complex [U(Cp*) 2Cl-(dddt)Na(thf)2] (1), and the salt-free compound [U(Cp*)2(dddt)] (2) could be extracted from 1 with toluene (Cp* = eta-C5Me5; dddt = 5,6-dihydro-1,4-dithiin- 2,3-dithiolate). Reduction of 2 with Na(Hg) or addition of Na2dddt to [U(Cp*)2Cl2Na(thf)x] in the presence of 18-crown-6 gave the first uranium(III) dithiolene compound, [Na(18-crown-6)(thf) 2][U(Cp*)2(dddt)] (4). The dimeric lanthanide complexes [{Ln(Cp*)2(dddt)K(thf)2}2] (Ln = Ce (5), Nd (6)) were prepared by reaction of [Ln(Cp*)2Cl 2K] with K2dddt, and in the presence of 15-crown-5, they were transformed into the cation-anion pairs [K(15-crown-5)2] [Ln(Cp*)2(dddt)] (Ln = Ce (7), Nd (8)). The crystal structures of 2, 4·thf, 5-7, 7·0.5(pentane), and 8·0.5(pentane) were determined by X-ray diffraction analysis. Comparison of the structural parameters of the anions [M(Cp*)2(dddt)]- (M = U, Ce, Nd) revealed that the U-S and U-C(Cp*) distances are shorter than those expected from a purely ionic bonding model; the relatively small folding of the dddt ligand suggests that the interaction between the C=C double bond and the metal center is weak, in agreement with the NMR observations in solution. The structural data obtained from molecular geometry optimizations on the complexes [M(Cp*)2(dddt)]-,0 (M = Ce, U) using relativistic density functional theory (DFT) calculations reproduce experimental trends. A detailed orbital analysis shows that the contraction of the metal-sulfur bond lengths when passing from [Ce(Cp*)2(dddt)] – to [U(Cp*)2(dddt)]- is partly related to the uranium 5f orbital-ligand mixing, which is greater than the cerium 4f orbital-ligand mixing. The comparison of the two [U(Cp*) 2(dddt)]-,0 species reveals a higher ligand-to-metal donation in the case of the U(IV) complex.
