Highlights

  • A novel 22-membered dinuclear metello-macrocycle has been synthesized.

  • Metello-macrocycle is the first example of tin(IV) complex which is achieved by simple decarbonylation of dibutyltin ladder.

  • Coordination pattern at the Sn(IV) centers has been established by spectroscopic studies and X-ray diffraction.

Abstract

The self-assembly of tetrabutyldistannoxane ladder {[nBu2Sn(LH)]2O}2 1 upon crystallization in xylene affords the novel cyclic dimer [nBu(LxH)Sn]2 2, featuring a 22-membered macrocycle. The dimer also contains a 2-fold linkage of neighbouring units via intermolecular Sn-O contacts, giving rise to polymeric 1D chains in which the tin atoms assume pentagonal bipyramidal environments by means of additional Sn-Ocatecholate contacts.

Graphical abstract

Unprecedented formation of dibutyltin(IV)-macrocycle via dibutyltin(IV) ladder in presence of xylene is described.

Notes

Synthesis of {[nBu2Sn(LH)]2O}2 (1); The reaction was carried out under a nitrogen atmosphere using standard Schlenk techniques. A suspension of nBu2SnO (0.46 g, 1.84 mmol) and LHH′ (0.5 g, 1.85 mmol) in 50 ml anhydrous toluene was refluxed for 10 h in a flask equipped with a Dean-Stark water separator and a water-cooled condenser. The orange coloured solution was filtered while hot and solvent evaporated from the filtrate in vacuo to give an orange residue that was washed thoroughly with

    As an important part of metal-based complexes, organotin derivatives exhibit abundant structural diversity, which have received great attention for a long period [1–5]. Up to now, a number of organotin derivatives with various structures, such as cubes, butterflies, ladders, drums, and polymers have been constructed [4–8]. For example, the tetrameric n-butyloxotin di-tert-butylphosphinate displays a cubic cluster [8], the dimeric n-butylhydroxytin bis(dicyclohexylphosphinate) is a “butterfly” cluster [8], and the 4-carboxybenzenesulfonamide diorganotin(IV) complexes adopt tetranuclear tin ladder-like structure containing two deprotonated ligands linked by three alternate Sn2O2 four-membered rings [9].
