LiHF2 crystallizes in the monoclinic C2/m space group. Li(1) is bonded to two equivalent H(1) and six equivalent F(1) atoms to form a mixture of distorted edge and corner-sharing LiH2F6 hexagonal bipyramids. H(1) is bonded in a distorted linear geometry to two equivalent Li(1) and two equivalent F(1) atoms. F(1) is bonded in a distorted single-bond geometry to three equivalent Li(1) and one H(1) atom.
LiHF2 crystallizes in the monoclinic C2/m space group. Li(1) is bonded to two equivalent H(1) and six equivalent F(1) atoms to form a mixture of distorted edge and corner-sharing LiH2F6 hexagonal bipyramids. Both Li(1)-H(1) bond lengths are 1.69 Å. There are two shorter (1.79 Å) and four longer (2.29 Å) Li(1)-F(1) bond lengths. H(1) is bonded in a distorted linear geometry to two equivalent Li(1) and two equivalent F(1) atoms. Both H(1)-F(1) bond lengths are 1.14 Å. F(1) is bonded in a distorted single-bond geometry to three equivalent Li(1) and one H(1) atom.
