Abstract:

The crystal structure of tetra(propyn-1-yl)silane, Si(C≡CMe)4 1, has revealed a completely asymmetric molecule (point group C1). Since this finding concerns a single crystal, the bulk material of 1 was studied by solid-state 29Si and 13C MAS NMR. This confirmed the result of the X-ray analysis, and by comparison with previous NMR measurements of the tin analogue 1(Sn) it is concluded that 1 and 1(Sn) must have very similar solid-state structures which are in contrast to those known for other tetra(alkyn-1-yl)silicon and -tin compounds. The NMR data set of 1 in solution was completed by determi

The crystal and molecular structures of Sn(O—t-Bu)4• and [Sn(O—i-Pr)4•HO—i-Pr]2 have been determined by single-crystal X-ray diffraction. Sn(O—t-Bu)4 crystallizes in the monoclinic crystal system with space group C2/c, where a = 17.382(6) Å, b = 8.742(2) Å, c = 15.518(5) Å, β = 116.44(1)°, Z = 4, and R = 2.5%.

Abstract:

The ternary stannide CeRuSn is a static mixed-valent cerium compound with an ordering of trivalent and intermediate-valent cerium on two distinct crystallographic sites. 119Sn Mössbauer spectra showed two electronically almost identical tin atoms at 323 K, while at 298 K and below (77 and 4:2 K) two tin sites can clearly be distinguished. Solid-state 119Sn NMR experiments were performed to probe the local hyperfine fields at the two different Sn sites. Powder 119Sn NMR spectra are nicely fitted with two Sn sites with nearly the same magnetic anisotropy, but with different absolute shift values

Abstract We report the first magic-angle spinning (MAS) nuclear magnetic resonance (NMR) study on Sn(NCN). In this compound the spatially elongated (NCN)2− ion is assumed to develop two distinct forms: either cyanamide (N≡C–N2−) or carbodiimide (−N=C=N−). Our 14N MAS NMR results reveal that in Sn(NCN) the (NCN)2− groups exist exclusively in the form of symmetric carbodiimide ions with two equivalent nitrogen sites, which is in agreement with the X-ray diffraction data. The 14N quadrupolar coupling constant | C Q | $\vert {C}_{\text{Q}}\vert $ ≈ 1.1 MHz for the −N=C=N− ion in Sn(NCN) is low whe

Abstract:

The primary lithium-carbon monofluoride (Li-CFx) cell offers the highest specific energy of any commercial lithium metal battery chemistry known. However, the practical discharge voltage even at low current densities (ca. 2.5-2.7 V) is significantly lower relative to the theoretical value (4.57 V), causing a significant penalty in specific energy. To reduce the overpotential at the CFx electrode, we altered the electrochemical reaction mechanism to defluorinating the CFx electrode upon discharge, without concomitant lithiation.

Abstract:

Abstract t-Butyloxytin(II) chloride (1) is prepared from SnCl2 and KO-z-Bu at -60 °C in tetrahydrofuran. Above -30 °C a reversible dismutation into SnCl2 and [(t-BuO)2Sn] is observed in THF. For this process Δ G = +38 kJ/mol is estimated from NMR data. Compound 1 is a centrosymmetric dimer in the solid state with bridging O atoms (Sn-O 2.153(2)/2.156(2) Å, O-Sn-O 73.0(1)°, Sn-O-Sn 107.0(1)°). Due to the acute intraring bond angles at Sn. the O···O distance across the four-membered ring is relatively short (2.563(3) Å). The dimers are very loosely connected to chains by bridging THF molecules.

Abstract:

A new series of tin(II) complexes (1, 2, 4, and 5) were successfully synthesized by employing hydroxy functionalized pyridine ligands, specifically 2-hydroxypyridine (hpH), 8-hydroxyquinoline (hqH), and 10-hydroxybenzo[h]quinoline (hbqH) as stabilizing ligands. Complexes [Sn(μ-κ2ON-OC5H4N)(N{SiMe3}2)]2 (1) and [Sn4(μ-κ2ON-OC5H4N)6(κ1O-OC5H4N)2] (2) are the first structurally characterized examples of tin(II) oxypyridinato complexes exhibiting {Sn2(OCN)2} heterocyclic cores. As part of our study, 1H DOSY NMR experiments were undertaken using an external calibration curve (ECC) approach, with te

Methylthioanilines, a series of sulfur-nitrogen donor ligands substituted with OCH3, CH3, Cl, and Br, and their copper(II) complexes have been synthesized and characterized by 1H and 13C NMR, elemental analysis, FTIR, UV-Vis and EPR spectra, molar conductance, and magnetic susceptibility measurements. The NMR spectra of the ligands revealed that the para/ortho protons and para carbon were sensitive to the electronic effect of substituents. The CHNS analysis presented CuLCl2 (L = OCH3, CH3, Cl) and CuL2Cl2 (L = Br) stoichiometries for the copper complexes. FTIR spectra showed that the bidentate

Abstract:

The high-capacity phosphorus- (P-) based anode materials for sodium-ion batteries (NIBs) often face poor performance retentions owing to the low conductivity and large volume expansion. It is thus essential to buffer these problems by appropriately alloying with other elements such as tin (Sn) and constructing well-designed microstructures. Herein, a series of P-/Sn-based composites have been synthesized by the facile and low-cost one-step ball milling. Pair distribution function (PDF) has been employed as a hardcore quantitative technique to elucidate their structures combined with other tech

Abstract:

The applications of the pH low insertion peptide (pHLIP) in cancer diagnosis and cross-membrane cargo delivery have drawn increasing attention in the past decade. With its origin as the transmembrane (TM) helix C of bacteriorhodopsin, pHLIP is also an important model for understanding how pH can affect the folding and topogenesis of a TM α-helix. Protonations of multiple D/E residues transform pHLIP from an unstructured coil at membrane surface (known as state II, at pH ≥ 7) to a TM α-helix (state III, pH ≤ 5.3). While these initial and end states of pHLIP insertion have been firmly establishe

AbstractReaction of the chelating imino-pyridine ligand SIMPY, (SIMPY=2-(DippN=CH)-C5H4N), Dipp=2,6-iPr2-C6H3, with germanium(II) and tin(II) halides provides the respective neutral complexes [SIMPY·EX2] (EX2: E=Ge, X=Cl, Br; E=Sn, X=Cl, Br, I). The method is readily extendable to give the tin(II) triflate complex [SIMPY·Sn(OTf)2] (OTf, triflate=CF3SO3−). In the solid state, the neutral compounds [SIMPY·EX2] exist as monomers, in which the four-coordinate tetrel atoms feature a slightly distorted disphenoidal geometry around germanium and tin.
