Polymeric [Li(NO₃)(monoglyme)]_n

W. A. Henderson, N. R. Brooks and W. H. Smyrl

Abstract: The title compound, catena-poly[[(1,2-dimethoxyethane)lithium(I)]--nitrato-O:O'], [Li(NO₃)(C₄H₁₀O₂)]_n, is a one-dimensional polymer. In the asymmetric unit, there are two Li⁺ cations and two monoglyme molecules located on crystallographic twofold axes and one NO₃^- anion on a general position. Both cations are coordinated by two ether O atoms from a single monoglyme. In addition, one cation is coordinated by two bidentate anions, making a six-coordinate Li⁺, and the other by two monodentate anions, making a four-coordinate Li⁺. Each NO₃^- anion is coordinated to two Li⁺ cations, to one in a monodentate fashion and to the other in a bidentate fashion. The one-dimensional Li(monoglyme)NO₃ chains are propagated by the 3₁ screw axis along the c axis, with alternating four- and six-coordinate Li⁺ cations.
