Abstract The synthesis and crystal structure of the new tetranuclear diphenyltin(IV) compound [\SnPh2\ \SnPh2(OCOMe)\(mu(2)-OMe)(mu(3)-O)](2) (1), generated from the reaction of [SnPh2Cl2] and NaOCOMe, are described. Single crystal X-ray diffraction revealed that 1 is a tetranuclear complex with four diphenyltin(IV) units which are inter-connected by mu(3)-oxido and mu(2)-methoxido bridges leading to a ladder-like Sn4O4 cluster. Structural comparison with related compounds found in crystallographic data base (CSD) attests that such tetranuclear systems are more abundant than related oxido bridged dimers or trimers. Complex 1 efficiently catalyzes the aerobic Baeyer-Villiger oxidation of cyclohexanone to epsilon-caprolactone, under mild conditions. With the sacrificial benzaldehyde method, quantitative conversion was observed in just 30 min with a remarkable selectivity. (C) 2018 Elsevier B.V. All rights reserved.
