Figure 1 The structure of the building unit of the one-dimensional of (I), with the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level. Uncoordinate water molecules and H atoms on C atoms have been omitted. [Symmetry codes: (A) 2 − x, 2 − y, 1 − z; (B) 1 − x, 2 − y, 1 − z; (C) −1 + x, y, z.] |
