Abstract
Crystals of the title compound are triclinic, space group P, with Z= 1 in a unit cell of dimensions a= 6.886(1), b= 7.916(2), c= 11. 358(2)Å, α= 90.30(2), β= 107.73(1), γ= 82.93(1)°. The structure was solved by conventional heavy-atom methods from 1 791 diffracted intensities measured on a diffractometer, and refined to R 0.024. The central chain of the molecule, Sn–Ru–Ru–Sn, is almost linear, and the carbonyl ligands, which lean slightly towards the outer SnMe3 groups, adopt an eclipsed configuration. The Ru–Ru bond [2.943(1)Å] is rather longer than the usual single-bond length, while Ru–Sn bond is correspondingly shorter [2.691(1)Å].Keywords
