(top) and (II)

(bottom). For clarity, the O atoms as well as the C—O bonds attached behind the rings are displayed as translucent. (In the electronic version of the paper, atom labels are coloured as in Fig. 2

.) [Symmetry codes: (i) x + $[1 \over 2]$ , −y + $[3 \over 2]$ , −z + 1; (ii) x + $[1 \over 2]$ , −y + $[1 \over 2]$ , −z + 1; (iii) x + $[1 \over 2]$ , −y + $[1 \over 2]$ , −z; (iv) x + $[1 \over 2]$ , −y + $[3 \over 2]$ , −z.]
