Polymeric [Li(NO3)(monoglyme)]n

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