Polymeric [Li(NO3)(monoglyme)]n

The title compound, catena‐poly­[[(1,2‐di­methoxy­ethane)­lithium(I)]‐μ‐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.
