Abstract

The title compound, tetra-μ3-tert-butoxy-tetra- μ4-tert-butoxy-tetralithiumtetrasodium, [Li4Na 4(C4H9O)8], has been obtained in a second, triclinic, modification, with three crystallographically independent molecules in the asymmetric unit. All three molecules, as well as the two independent molecules of a previously reported monoclinic polymorph, have essentially the same structure, in which the tert-butoxy ligands are either triply or quadruply bridging, Li+ cations have trigonal pyramidal coordination, and Na+ cations have irregular fourfold coordination. The molecules have no crystallographic symmetry, but approximate to 4̄2m (D2d) symmetry. © 2003 International Union of Crystallography Printed in Great Britain - all rights reserved.
