- Аннотация: The mixed-valence [mu]-oxide Sn12 cluster, decacarbonyltetra-[mu]4-oxido-hexa-[mu]3-oxido-tetrakis[[mu]-2,2'-(pyridine-2,6-diyl)bis(1,1-diphenylethanolato)]decatin(II)ditin(IV)dimolybdenum(O)(2 Mo-Sn) toluene heptasolvate, [Mo2Sn12(C33H27NO2)4O10(CO)10]·7C7H8, has a crystallographically imposed inversion centre. The asymmetric unit also contains three and a half toluene solvent molecules, one of which is disordered about a centre of symmetry. The complex molecule comprises six distinct Sn atom species with four different coordination numbers, namely 3, 4, 5, and 6. The SnII atoms forming the central Sn10O10 core adopt distorted trigonal-pyramidal, square-pyramidal and octahedral coordination geometries provided by the [mu]-oxide atoms and by the O- and N-donor atoms of two pyridinediethanolate ligands. The terminal SnIV atoms have distorted trigonal-bipyramidal coordination geometries, with a [mu]4-oxide atom and the N atom of a pyridinediethanolate ligand occupying the axial positions, and the Mo atom of a Mo(CO)5 group and the alkoxy O atoms of a ligand forming the equatorial plane. In the crystal, weak intra- and intermolecular C-H...O hydrogen bonds are observed.
