Bis(4-fluoro-benz-yl-κC)bis-(3-methyl-sulfanyl-1,2,4-thia-diazole-5-thiol-ato-κN,S)tin(IV).

The mononuclear title molecule, [Sn(C(7)H(6)F)(2)(C(3)H(3)N(2)S(3))(2)], has 2 symmetry. The Sn(IV) atom, located on a twofold rotation axis, is in a skew trapezoidal-bipyramidal geometry, with the basal plane defined by two S,N-chelating 3-methyl-sulfanyl-1,2,4-thia-diazole-5-thiol-ate ligands. The apical positions are occupied by the C atoms of two 4-fluoro-benzyl groups.

The crystal structure of the title compound, [Na(C(3)H(3)N(2)S(3))(H(2)O)(2)](n), features polymeric chains made up of O⋯O edge-shared NaSN(H(2)O)(4) units running along the b axis. The Na(+) ion and all non-H atoms of the thia-diazole ligand lie on a mirror plane.
