Figure 2
The packing structure of (I

) with a ten-membered hydrogen-bonded ring of a [2 $[\overline 1]$ 0] sheet centred around the inversion centre at ( $[{1 \over 2}]$ ,0, $[{1 \over 2}]$ ) (all $[\overline 1]$ are indicated with small circles) and crosslinked along [001] with two [ $[\overline 2]$ 10] sheets. H atoms not participating in the hydrogen bonding have been omitted. Atoms labelled with the suffix A lie at positions (1 − x, −y, 1 − z), B at (−x, −2 − y, 1 − z), C at (1 + x, 2 + y, z), D at (x + $[{1 \over 2}]$ , −y − $[{1 \over 2}]$ , z + $[{1 \over 2}]$ ), E at ( $[{1 \over 2}]$ − x, y + $[{1 \over 2}]$ , $[{1 \over 2}]$ − z), F at ( $[{3 \over 2}]$ − x, y + $[{1 \over 2}]$ , $[{3 \over 2}]$ − z), G at (x − $[{1 \over 2}]$ , −y − $[{1 \over 2}]$ , z − $[{1 \over 2}]$ ), H at (x + $[{1 \over 2}]$ , $[{1 \over 2}]$ − y, z + $[{1 \over 2}]$ ) and J at ( $[{1 \over 2}]$ − x, y − $[{1 \over 2}]$ , $[{1 \over 2}]$ − z).
