At ambient temperature, the title compound, C16H14O3, is triclinic, with then-butyl side chain disordered in an out-of-plane orientation. On cooling below 240 K, it converts into a different triclinic phase with an ordered planar conformation and denser packing, which is retained on warming to room temperature. The transition (occasionally) proceeds from single crystal to single crystal.
在常温下,标题化合物
C16H14O3 呈三棱相,侧链的正丁基在平面外无序排列。冷却到 240 K 以下时,它会转化为另一种三菱相,具有有序的平面构象和更密集的堆积,升温到室温时仍保持这种状态。这种转变(偶尔)是从单晶到单晶的转变。
