Sažetak
A series of alkali salts of hydrogenbromanilic acid trihydrates (K+, Rb+ and Cs+), bromanilic acid tetrahydrate (Na+), and bromanilic acid dihydrates (K+, Rb+, and Cs+) were prepared and studied by single-crystal X-ray diffraction. Their crystal packings are dominated by stacking of quinoid rings. The monoanionic quinoid rings pack face-to-face without offset and with short centroid separations (3.25 – 3.30 Å), while the dianionic rings form offset stacks (1.4 – 1.8 Å) with larger centroid separation (3.8 – 4.1 Å).
