Figure 2 Partial packing view of compound (I) , showing the formation of chains along the b axis built from hydrogen bonds, and the formation of R 42(18) and R22(8) rings. For the sake of clarity, H atoms not involved in hydrogen bonding have been omitted·[Symmetry codes: (i) −x, −y + 1, −z + 1; (ii) −x, −y + 2, −z + 1] |
