“…To our knowledge, up to now, twelve depositions have been reported, corresponding to ten distinct compounds. The first structure of such a compound was reported in 1997 by R. Borsdorf et al for [(n-Bu2Sn-Pyr)2(CO3)] ( 14) [43]. Compound 14 was isolated as orange crystals from the reaction in methanol involving an equimolar mixture of n-Bu2SnO and Regarding X-ray crystallographic structures, diorganotin derivatives are the most represented carbonato tin complexes in CSD.…”

This review focuses on organotin compounds bearing hemicarbonate and carbonate ligands, and whose molecular structures have been previously resolved by single-crystal X-ray diffraction analysis. Most of them were isolated within the framework of studies devoted to the reactivity of tin precursors with carbon dioxide at atmospheric or elevated pressure. Alternatively, and essentially for the preparation of some carbonato derivatives, inorganic carbonate salts such as K2CO3, Cs2CO3, Na2CO3 and NaHCO3 were also used as coreagents. In terms of the number of X-ray structures, carbonate compounds are the most widely represented (to date, there are 23 depositions in the Cambridge Structural Database), while hemicarbonate derivatives are rarer; only three have so far been characterized in the solid-state, and exclusively for diorganotin complexes. For each compound, the synthesis conditions are first specified. Structural aspects involving, in particular, the modes of coordination of the hemicarbonato and carbonato moieties and the coordination geometry around tin are then described and illustrated (for most cases) by showing molecular representations. Moreover, when they were available in the original reports, some characteristic spectroscopic data are also given for comparison (in table form). Carbonato complexes are arbitrarily listed according to their decreasing number of hydrocarbon substituents linked to tin atoms, namely tri-, di-, and mono-organotins. Four additional examples, involving three CO2 derivatives of C,N-chelated stannoxanes and one of a trinuclear nickel cluster Sn-capped, are also included in the last part of the chapter.

“…An orange derivative [143] uses a carbonate group as a bridging tridentate ligand, two of the oxygen atoms bonded to one tin(IV) atom and the remaining oxygen bonded to the other tin(IV). The former tin atom has a pentagonal bipyramidal environment with two butyl groups in apical sites (Sn0 2 N 2 C 2 S) and the latter tin in a trigonal bipyramidal environment with butyl groups in apical sites (SnC 2 ONS).…”

This review covers the crystallographic data of organotin compounds containing two tin centres, with a view to identifying correlations between properties and structure. Almost two hundred and fifty such compounds are included, of which almost thirty contain Sn 2 +6 units with a direct Sn-Sn bond, the shortest being 269.1(1) pm. There are ten compounds with tin in the +2 oxidation state, with a shortest Sn(ll)-Sn(ll) bond distance of 276.4(2) pm. The remainder of the compounds contain tin(IV), and the shortest Sn(IV)-Sn(IV) distance is 294 pm. The predominant geometries for tin(IV) are tetrahedral and trigonal bipyramidal. Distortion and cis-trans isomerism are found, the former being most common. In one example of distortion isomerism crystallographically independent molecules occur within the same unit. Several types of bridging are observed between the tin centres. Relationships between bond distances, ligand size and angles are discussed in the respective sections. The most common bridge donor atom is oxygen. The most common carbon donor ligands are phenyl and methyl groups.

Organotin(IV) compounds are known to promote the direct synthesis of organic carbonates from carbon dioxide and alcohols. In the past, structural studies have highlighted that the carbonato moiety is a recurring ligand of tin species collected during the CO2 pressurized reactions. In a mimetic approach and in order to achieve an available and recyclable precursor, the title compound, (n-Bu2Sn)2O(CO3) (1) was prepared in a single step by reacting commercial di-n-butyltin dichloride with an aqueous solution of sodium carbonate. 1 was characterized by infrared spectroscopy, thermogravimetric and elemental analysis.Multinuclear NMR investigations in solution were also conducted. 1 was then evaluated for the direct carbonation of alcohols (methanol, ethanol, n-butanol and isopropanol) under CO2 pressure. Recycling experiments were performed showing the efficient reuse of 1 without loss of activity. Furthermore the infrared fingerprint of 1 was preserved even after several runs demonstrating a good stability. The effects of pressure and of reaction time on the DMC formation were also studied.
