The dependence of bond distances: (a) D2 on D4 for structures that were originally determined as 2-hydroxy-3,5-dinitrobenzoate (II), or as containing 2-hydroxy-3,5-dinitrobenzoic acid (I); (b) D1 on D3 for the structures that were determined as 2-carboxy-4,6-dinitrophenolate (III). Colour code for symbols: black squares are the data retrieved from the CSD; red circles are the corrected title structures; green and blue triangles are the original and the corrected structure of LUDFUL, which contains a molecule of 2-hydroxy-3,5-dinitrobenzoic acid (I). |
