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

The Sn, Cl and water O atoms of the title compound, [Sn(2)(CH(3))(4)Cl(4)(H(2)O)(2)]·C(10)H(20)O(5), lie on a special position of 2 site symmetry. The Sn(IV) atom shows cis-C(2)SnCl(2)O trigonal–bipyramidal coordination [C—Sn—C = 157.0 (1)°]; however, two [Me(2)SnCl(2)(H(2)O)] 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 a mer-C(2)SnCl(3)O 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/m site.
