Simplifications of the crystal structure of bix·2H2O in polymorph (II), showing (a) a schematic view of the formation of a single three-dimensional network and (b) a schematic view of the formation of the fivefold interpenetrated network. [In (a), in the electronic version of the paper, blue and aqua balls represent R44(8) water units and bix molecules, respectively.] |
