“…This is the case for (cyclopenta-2,4-dien-1-yl)-(2-(dimethylaminomethyl)phenyl)diphenyl tin (refcode IHOZAH) [93] (Fig. 15, left), where the intramolecular C-Sn···N distance corresponds to an Nc value of 0.74 and the C-Sn···N angle is 171.08°, congruent with an attractive interaction between the lone pair of the tertiary amine nitrogen and the σ-hole along the extension of the C-Sn covalent bond.…”

Close contacts involving germanium and tin in crystal structures: experimental evidence of tetrel bonds

Modeling indicates the presence of a region of low electronic density (a Bσ-hole^) on group 14 elements, and this offers an explanation for the ability of these elements to act as electrophilic sites and to form attractive interactions with nucleophiles. While many papers have described theoretical investigations of interactions involving carbon and silicon, such investigations of the heavier group 14 elements are relatively scarce. The purpose of this review is to rectify, to some extent, the current lack of experimental data on interactions formed by germanium and tin with nucleophiles. A survey of crystal structures in the Cambridge Structural Database is reported. This survey reveals that close contacts between Ge or Sn and lone-pair-possessing atoms are quite common, they can be either intra-or intermolecular contacts, and they are usually oriented along the extension of the covalent bond formed by the tetrel with the most electron-withdrawing substituent. Several examples are discussed in which germanium and tin atoms bear four carbon residues or in which halogen, oxygen, sulfur, or nitrogen substituents replace one, two, or three of those carbon residues. These close contacts are assumed to be the result of attractive interactions between the involved atoms and afford experimental evidence of the ability of germanium and tin to act as electrophilic sites, namely tetrel bond (TB) donors. This ability can govern the conformations and the packing of organic derivatives in the solid state. TBs can therefore be considered a promising and robust tool for crystal engineering.

“…In our recent paper, we described the preparation, structure and reactivity of triorganotin(IV) cyclopentadienides, hydrides and distannanes bearing L CN ligand [6]. Now we would like to report on structure and properties of analogous diorganotin(IV) distannanes containing L CN RSn moiety, where R is n-Bu and L CN , respectively.…”

“…The solution NMR spectra were recorded in CDCl 3 , benzened6 and dimethyl sulfoxide (DMSO)-d6 on a Bruker Avance 500 spectrometer (equipped with a Z-gradient 5 mm probe) at frequencies 1 H (500.13 MHz), 13 119 Sn NMR spectra were measured using the inverse gated-decoupling mode.…”

“…The 1 H and 119 Sn NMR spectra of all prepared compounds were measured in CDCl 3 (except for 6, which was measured in benzened6) at 295 K. Owing to the limited solubility of compounds in noncoordinating solvents, not all 13 C NMR spectra were measured and low-temperature measurements were not performed. All recorded 1 H NMR spectra are in good conformity with the proposed composition of each compound with respect to the nature and number of each substituent.…”
