Abstract

The title compound, C(10)H(8)O(4), was isolated from the fermentation culture of the endophytic fungus Cephalo-sporium sp. In the crystal structure, mol-ecules are connected into a one-dimensional chain along [101] by inter-molecular O-H⋯O hydrogen bonds involving the hydroxyl and carbonyl functionalities. The chains are linked by non-classical C-H⋯O inter-actions, forming extended two-dimensional layers approximately parallel to (11).

摘要

标题化合物C(10)H(8)O(4)是从内生真菌头孢霉属（Cephalo-sporium sp.）的发酵培养物中分离得到的。在晶体结构中，分子通过涉及羟基和羰基官能团的分子间O-H⋯O氢键沿[101]方向连接成一维链。这些链通过非经典的C-H⋯O相互作用相连，形成大致平行于(11)的扩展二维层。
