Amine adduct with tin (II) chloride: Synthesis, molecular structure characterization, and DFT computational studies

N-Donor stabilized tin(ii) cations as efficient ROP catalysts for the synthesis of linear and star-shaped PLAsviathe activated monomer mechanism

“…This contrasts with the related N-donor ligands, [15][16][17][18][19][20] which provide the product of the auto-ionization reaction along with the free ligand under the same conditions. 25,26 Moreover, the molecular structure of 2 was determined by the single-crystals X-ray diffraction analysis (Figure 1). Suitable single crystals of 2 were obtained from a saturated CH2Cl2 solution at room temperature.…”

“…The N1-Sn1 bond distance (2.3465(18) Å) falls to the region (2.284 -2.585 Å) typical for N→Sn coordination bonds found in D→SnCl2 adducts (D = TMEDA, 1-vinylimidazole, 1benzylimidazole, 1,2,4-triazole, bipyridine, phenanthroline). [25][26][27] On the other hand, the N2-Sn1 bond distance (2.6493(17) Å) is somewhat longer and indicates a weaker donor ability of the imine CH=N group in 2.…”

Low‐Temperature Sn0 Nanoparticles Synthesis by Means of Tin(II) N,N‐Complexes Reduction

“…The 119 Sn NMR spectrum of 1 revealed signal −219.5 ppm (δ=−235.5 ppm for 2 ). The values are shifted upfield when compared to the related complex [TMEDA→SnCl 2 ] (δ=−165.0 ppm) [25] suggesting higher electronic shielding of the tin atom in 1 and 2 due to the strong CH=N→Sn coordination. In addition, the tin atom is sterically protected by t Bu groups of the CH=N moiety in 1 , while the shielding of the Sn atom is arranged by the Ph group in the ortho position of the pyridine in 2 .…”

Electrodeposition of Tin onto Zinc for the Electrochemical Synthesis of Zn/Sn/Cu Precursor Stack for CZTS‐Based Photoconversion Devices

“…These are representative of the methylene protons affected by the electronic interactions with Sn, promoting a different environment in the sample and resulting in a chemical shift of the peaks. The results are consistent with literature cases, where DEA has been proved to form complexes with divalent metals using both the amine and the hydroxyl groups. Small peaks of a different species (about 5 % compared to the main species) can be also detected at 4.87, 3.59, and 2.69 ppm (Figure S2).…”
