Three-dimensional hydrogen-bonded structures in the guanidinium salts of the monocyclic dicarb­oxy­lic acids rac-trans-cyclo­hexane-1,2-dicarb­oxy­lic acid (2:1, anhydrous), isophthalic acid (1:1, monohydrate) and terephthalic acid (2:1, trihydrate)

Figure 3
The molecular configuration and atom-numbering scheme for the guanidinium cation (A), the benzene-1,4-dicarboxylate dianion and the two solvent water molecules in the asymmetric unit of (III)

. The dianion lies across an inversion centre [symmetry code: (ii) −x + $[{3\over 2}]$ , −y + $[{1\over 2}]$ , −z + 1], while water molecule O1W lies on the twofold rotation axis at ( $[{1\over 2}]$ , y, $[{3\over 4}]$ ). Displacement ellipsoids are drawn at the 40% probability level. Dashed lines indicate hydrogen bonds.
