Figure 1
A view of (I) along the b axis, showing the atom labeling and displacement ellipsoids at the 20% probability level. Atoms Li1, O3A, Li1A and O3 form Li2O2 ring A, and atoms Li1, O3B, Li1B and O3C form ring B. Two adjacent phosphonate groups are connected by a symmetric hydrogen bond (P1—O1—H4⋯O1C—P1C). Selected distances (Å): O1⋯O1C = 2.472 (3); Li1—O3 = 1.962 (4); Li1—O3A = 1.905 (3). Selected angles (°): O3A—Li1—O3 = 91.29 (7); O3B—Li1—O3 = 109.6 (3); O3C—Li1—O3 = 121.81 (9); O3B—Li1—O3A = 121.81 (9); O3C—Li1—O3A = 123.0 (3); O3B—Li1—O3C = 91.29 (7). [Symmetry codes: (A) 1 − x, 1 − y, 1 − z; (B) 1 − x, y, ![[{1\over 2}]](teximages/sq3018fi6.gif) − z; (C) x, 1 − y, − + z; Li1B is at (1 − x, 1 − y, −z); Li1C is at (x, y, −1 + z).] |
