title: Bis(dimethyl sulfoxide-κO)bis(saccharinato-κN)-zinc(II).
abstract: The title compound, [Zn(C(7)H(4)N(2)O(3)S)(2)(C(2)H(6)OS)(2)], is a neutral four-coordinate complex with a tetra-hedral geometry. The metal atom is surrounded by the two dimethyl sulfoxide (DMSO) ligands, each coordinating through the O atom, and two anionic saccharinate (1,1,3-trioxo-2,3-dihydro-1λ(6),2-benzo-thia-zol-2-ide) ligands coordinating through the N atom. The tetra-hedral geometry is slightly distorted as is evident from the N-Zn-N bond angle of 113.85 (6)°, the O-Zn-O bond angle of 98.92 (6)° and O-Zn-N bond angles of 116.96 (6) and 103.93 (6)°. The Zn-N bond lengths are 1.9742 (15) and 2.0025 (16) Å. The Zn-O bond lengths are 1.9806 (14) Å and 1.9468 (14) Å. The DMSO ligand coordinates through the lone pair of electrons on the O atom, as can be seen from the Zn-O-S bond angle of 131.30 (8)°.
