Figure 8
(a) The intermolecular hydrogen bonds (dashed lines) and (b) the packing of the molecules in the crystal structure of B1

. The structure contains four distinct hydrogen bonds, designated a (N5—H5A⋯N45ⁱ), b (C11—H11A⋯O12ⁱⁱⁱ), c (C44—H44⋯O22ⁱⁱ) and d (N5—H5B⋯O22^iv). [Symmetry codes: (i) x, y + 1, z; (ii) x, −y, z − $[{1\over 2}]$ ; (iii) −x + $[{1\over 2}]$ , y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (iv) x, −y + 1, z − $[{1\over 2}]$ .]
