Figure 2
A view of the supramolecular layer in the title compound, shown in projection down the b axis. The hydroxy-O1—H⋯O2(hydroxy) hydrogen bonds are shown as orange dashed lines while both the hydroxy-O2—H⋯N4(terminal-piperazine) and (coordinated-piperazine)-N3—H⋯O1(hydroxy) hydrogen bonds are shown as blue dashed lines. The methine-C—H⋯S and S⋯S interactions within the layers (see text) are not shown. Only acidic hydrogen atoms are shown. |
