Figure 2
(a) Part of the crystal structure of (I), showing the formation of a two-dimensional net with centrosymmetric R44(16), R22(14) and R22(22) rings. (b) A diagram showing how the nets are linked in the c direction by pairs of N—H⋯S hydrogen bonds to generate R22(8) rings. In each case, hydrogen bonds are shown as dotted lines. The symmetry codes (i), (ii) and (iii) are as defined in Table 2. |
