A partial view of the molecular packing in (III). Dotted lines indicate the shortest O⋯O intermolecular distances [O3⋯O3ii = O3iii⋯O3iv = O3v⋯O3vi = 4.284 (2) Å; symmetry codes: (ii) −x + 1, −y + 1, −z + 2; (iii) −x + 1, y − , −z + ; (iv) x, −y + , z − ; (v) x, y, z − 1; (vi) −x + 1, −y + 1, −z + 1]. |
