“…The silicon atoms in compounds 2 – 4 each show a distorted-tetrahedral configuration with bond angles ranging from 106.1(2)° (C(12)–Si(2)–C(16); 4 ) to 114.9(2)° (C(21)–Si(1)–C(11); 4 ). The Sn–C and Fe–C bond lengths in all these compounds are in the range of those found in the literature. ,,− …”

The synthesis is reported of the crown ether substituted tin-containing ferrocenophanes fc(SiMe 2 CH 2 ) 2 Sn-(X)CH 2 CH(CH 2 OC 2 H 4 OCH 2 ) 2 (1, X = Ph; 2, X = I; 3, X = Cl; 4, X = F) and of the ditopic complex 3•LiCl. The compounds were characterized by multinuclear NMR spectroscopy, single-crystal X-ray diffraction analysis, and cyclic voltammetry. DFT calculations revealed important twoelectron stabilization in 3 and 4 due to intramolecular O→Sn coordination that is absent in 2.

“…There are similar molecular structures in the remaining three compounds [109][110][111], They consist of two ferrocene moieties linked to each other via tin atoms. Each iron atom is sandwiched (FeC ]0 ) and each tin atom is tetrahedrally coordinated, SnC 4 [109,110] and SnC 3 l [111].…”

In total, 430 heterotetranuclear iron clusters have been included in this review, containing the Fe 3 M, Fe 2 M 2 , Fe 2 MM', FeM 2 M' and FeMM'M" cores. About 25 % of the clusters contain non-transition metals (17 different elements). The shortest bond is the Fe-Ge bond of 2.321(10) A. The remaining examples (about 75 %) contain transition metals (21 different elements) in clusters with iron displaying a rich and complex chemistry. The shortest bond in this category is the Fe-Ni bond of 2.277(11) Ä. Correlations between structural parameters containing heteronuclear and ligand donor atoms are given. Furthermore, an overall summary of the metal-metal distances is given and the observed trends are discussed.

“…reported some derivatives such as 11 (Scheme ), which was obtained by a coupling reaction of a di(chlorostannane) with a di‐Grignard reagent. Interestingly, the reaction of 11 with iodine replaces one of the phenyl substituents at each tin atom in 11 with exclusive formation of the anti product …”

1,16‐Di‐tert‐butyl‐1,16‐diphospha[5.5]ferrocenophane: Synthesis, Reactions and Mössbauer Spectroscopy

et al. 2018

1,16‐Di‐tert‐butyl‐1,16‐diphospha[5.5]ferrocenophane was prepared in 76% yield by deprotonation of 1,1’‐di(2‐tert‐butylphosphanylethyl)ferrocene followed by treatment with 1,1’‐di(2‐bromoethyl)ferrocene. The ferrocenophane exists as a mixture of syn and anti diastereomers, which were separated by repeated precipitation of one of them. Reaction with borane afforded the respective borane adducts in 47% yield. Methylation with iodomethane gave the respective diphosphonium salt in quantitative yield. Oxidation with 1.0 or 5.0 equivalents of silver hexafloroantimonate gave a green and a blue material, respectively, presumably the mono and the diferrcenium salts. 1,16‐Di‐tert‐butyl‐1,16‐diphospha[5.5]ferrocenophane and its oxidation products were subjected to a temperature‐dependent Mössbauer effect (ME) study to elucidate their dynamical and paramagnetic relaxation characteristics. The ME data are consistent with the absence of spin averaging for the two distinct Fe sites in the monooxidation product over the temperature range 91
