In the title compound, C(13)H(9)NO(8)·CH(3)OH, the main mol-ecule possesses three carb-oxy-lic acid groups, which are asymmetrically distributed around the mol-ecule core. This results in hydrogen-bonding motifs ranging from a chain to various rings. The combination of the chain motif together with a carb-oxy-lic dimer R(2) (2)(8) ring motif creates a ribbon of mol-ecules propagating along the c-axis direction. A second ribbon results from the combination of the chain motif together with a methanol solvent mol-ecule and carboxyl-containing R(4) (4)(12) ring motif. These two ribbons combine alternately, forming a hydrogen-bonded layer of mol-ecules parallel to (2[Formula: see text]0).
在标题化合物C₁₃H₉NO₈·CH₃OH中，主体分子含有三个羧酸基团，它们围绕分子核心呈不对称分布。这导致氢键模式从链状到各种环状不等。链状模式与羧酸二聚体R₂²(8)环模式相结合，形成了沿c轴方向延伸的分子带。第二条分子带是由链状模式与甲醇溶剂分子以及含羧基的R₄⁴(12)环模式相结合产生的。这两条分子带交替组合，形成了平行于(20)的分子氢键层。
