Di-μ-chlorido-bis[aquachloridodimethyltin(IV)]–1,4,7,10,13-pentaoxacyclopentadecane (1/1)

Abstract

The Sn, Cl and water O atoms of the title compound, [Sn2(CH3)4Cl4(H2O)2]·C10H20O5, lie on a special position of 2 site symmetry. The SnIVatom showscis-C2SnCl2O trigonal–bipyramidal coordination [C—Sn—C = 157.0 (1)°]; however, two [Me2SnCl2(H2O)] units are linked by a tin–chlorine bridge [Sn←Cl = 3.247 (1) Å] across a center of inversion, generating a dinuclear species, so that the geometry is better regarded as amer-C2SnCl3O octahedron. The crown ether interacts through O—H...O hydrogen with the metal atom through the coordinated water molecules in an outer-sphere manner, generating a hydrogen-bonded chain running along [101]. The 15-crown-5 molecule is disordered over the 2/msite.
