, showing the hydrogen-bonded chain consisting of molecules B which runs parallel to [101]. Atoms labelled with an asterisk (*), hash symbol (#) or dollar sign ($) are at the symmetry positions (x + $[{1\over 2}]$ , −y + $[{1\over 2}]$ , z + $[{1\over 2}]$ ), (x − $[{1\over 2}]$ , −y + $[{1\over 2}]$ , z − $[{1\over 2}]$ ) and (x + 1, y, z + 1), respectively. Hydrogen bonds are shown as dashed lines and uninvolved H atoms have been omitted.
