It is a dark purple to black crystalline solid that is soluble in organic solvents. It is an easily made building block for many organic and organometallic compounds. ==Structure== The C5O core of the molecule is planar and conjugated. The C2-C3 and C4-C5 distances are 1.35 Å, while the C1-C2, C3-C4, C5-C1 are closer to single bonds with distances near 1.5 Å.〔 The phenyl groups of tetraphenylcyclopentadienone adopt a "propeller" shape in its 3D conformation. The four phenyl rings are rotated out of the plane of the central ring because of steric repulsion with each other. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tetraphenylcyclopentadienone」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
