Dilithium 1,2,5-thiadiazolidine-3,4-dione 1,1-dioxide dihydrate

D. W. McOwen, S. A. Delp, P. D. Boyle and W. A. Henderson

Abstract top

The title compound, poly[[mu]-aqua-aqua-[mu]6-(1,1-dioxo-1[lambda]6,2,5-thiadiazolidine-3,4-diolato)-dilithium], [Li2(C2N2O4S)(H2O)2]n or (H2O)2:Li2TDD, forms an infinite three-dimensional structure containing five-coordinate (Li/5) and six-coordinate (Li/6) Li+ cations. Li/5 is coordinated by three water molecules, one carbonyl O atom and one sulfuryl O atom while Li/6 is coordinated by one water molecule, three carbonyl O atoms, and two sulfuryl O atoms. Each water molecule bridges two Li+ cations, while also hydrogen bonding to either one endocyclic N atom and one sulfuryl O atom or two endocyclic N atoms. While the endocyclic N atoms in the anion do not coordinate the Li+ cations, the carbonyl and sulfuryl groups each coordinate three Li+ cations, which gives rise to the infinite three-dimensional structure.

Comment top

Dilithium 1,2,5-thiadiazolidine-3,4-dione 1,1-dioxide (Li2TDD) was synthesized following methods reported in the literature for the anion (Lee et al., Wen et al.). The salt forms a dihydrate in which the carbonyl and sulfuryl oxygen atoms each coordinate multiple Li+ cations forming a highly aggregated structure. In addition, each water molecule bridges two Li+ cations. The endocyclic nitrogen atoms, however, are not coordinated to the Li+ cations, indicating that the O atoms atoms exhibit the greatest Lewis basicity.

Experimental top

Sulfamide (1.00 eq.) was dissolved in methanol and slowly added to a solution of LiMeO (2.10 eq.) at room temperature, resulting in a cloudy white solution. After addition of diethyl oxalate (1.05 eq.), the solution became clear. After gently refluxing for 20 h, the solvent was removed under vacuum and a clear viscous solution was obtained. Upon addition of deionized water, crystals suitable for characterization formed.

Refinement top

The structure was solved by direct methods using the XS program. All non-hydrogen atoms were obtained from the i nitial solution. The hydrogen atoms were introduced at idealized positions and were allowed to refine isotropically. The structural model was fit to the data using full matrix least-squares based on F2. The calculated structure factors included corrections for anomalous dispersion from the usual tabulation. The structure was refined using the XL program from SHELXTL, graphic plots were produced using the ORTEP-3 crystallographic program suite.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R– factors based on ALL data will be even larger.
