Figure 3
Partially labelled illustration of the inorganic core of three hydrogen-bonded molecules of (I). Displacement ellipsoids are drawn at the 40% probability level. H and C atoms have been omitted for clarity. Ct1 and Ct2 are the inversion centres, with coordinates (0, 0, ) and (0, , 0), respectively. O atoms involved in complementary hydrogen bonding are linked by dashed bonds. [Symmetry codes: (i) −x, −y, −z + 1; (ii) −x, −y + 1, −z.] |
