A lithium complex of a bis­(amido)bis­(imido)silicate dianion

The title compound, bis­[μ₃-bis­(tert-butyl­amido)bis­(tert-butyl­imido)sil­yl]di-μ₃-chloro-tetra­tetra­hydro­furan­hexa­lithium(I), [Li₆(C₁₆H₃₈N₄Si)₂Cl₂(C₄H₈O)₄], crystallizes as a dimer of two contact ion pairs linked together by two mol­ecules of lithium chloride. The two halves of the mol­ecule are related by a crystallographic twofold rotation axis.

Special details

Experimental. NMR (300 MHz, 298 K, d⁸-THF) ¹H: 1.23, 1.13, 1.09 [s, 36H, C(CH₃)₃], 3.64, 1.78 [m, 16H, C₄H₈O]. ²⁹Si: -60.3 [br s]. ⁷Li: 1.22 (s), 0.21 (s).

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.
