(a) The structure of the (010) layer in (A). One can see chains of semi-oxalate anions along [201], and chains of alternating glycinium cations and semi-oxalate anions along [001]. (b) Undulating chains of semi-oxalate anions, viewed along [20]. Glycinium cations have been omitted for clarity. Hydrogen bonds are shown as dashed lines. |
