N2 - The title compounds, poly[[[bis(2-methoxyethyl) ether]-lithium(I)]-di-μ3-trifluoromethanesulfonato-lithium(I)], [Li2-(CF3SO3)2(C6H14O3)]n, and poly[[[bis(2-methoxyethyl) ether]-lithium(I)]-di-μ3-trifluoroacetato-dilithium(I)- μ3-trifluoroacetato], [Li3(C2F3 O2)3(C6H14 O3)]n, consists of one-dimensional polymer chains. Both structures contain five-coordinate Li+ cations coordinated by a tridentate diglyme [bis(2-methoxyethyl) ether] molecule and two O atoms, each from separate anions. In both structures, the [Li(diglyme)X2]- (X is CF3SO3 or CF3CO2) fragments are further connected by other Li+ cations and anions, creating one-dimensional chains. These connecting Li+ cations are coordinated by four separate anions in both compounds. The CF3SO3- and CF3CO2- anions, however, adopt different forms of cation coordination, resulting in differences in the connectivity of the structures and solvate stoichiometries.
