Systematic co‐crystallizations resulting in a total of six new crystal structures involving either 3‐hydroxy‐ or 4‐hydroxybenzoic acid, complemented by calculated molecular electrostatic potential surfaces and existing structural data, have shown that in a competitive molecular recognition situation, the OH moiety is a more effective hydrogen‐bond donor than the COOH moiety which, in turn, highlights
导致总共六个新的晶体结构的任一涉及3-羟基或4-羟基苯甲酸系统的共结晶,由下式计算分子静电势的表面上和现有的结构数据的补充,已经表明,在有竞争力的分子识别的情况, OH OH OH COOH is是一个更有效的氢键供体,这反过来凸显了静电荷比酸度可提供更多有用的指导来预测竞争性氢键偏好。
