View of the sheet formed by the inter­connection of three C—H⋯O hydrogen bonded chains in compound (2b). Hydrogen atoms not involved in the hydrogen bonding have been omitted for clarity. [Symmetry codes (from bottom to top rows and left to right). Bottom: −x + 1, y − [{1\over 2}], −z + [{3\over 2}]; −x + 1, y + [{1\over 2}], −z + [{3\over 2}]. Middle: x, −y, z; x, y, z; x, y + 1, z. Top: −x, y − [{1\over 2}], −z + [{3\over 2}]; −x, y + [{1\over 2}], −z + [{3\over 2}].]
