A prototype of this motif is ()2-.〔Sappa, E.; Tiripicchio, A.; Carty, A. J.; Toogood, G. E., "Butterfly Cluster Complexes of the Group VIII Transition Metals," in Progress in Inorganic Chemistry, 1987, vol. 35, p. 437.〕 Most butterfly clusters have additional bridging ligands. One inexample is the tetraphosphide Rh4(CO)5(PPh2)5-. A carbide-containing butterfly cluster is ()2-. Bonding in such clusters is often discussed in the context of polyhedral skeletal electron pair theory. This theory predicts that tetrametallic clusters with 60 valence electrons will adopt tetrahedral geometry with six M-M bonds. Tetrahedral clusters is classified as nido clusterrs. By addition of 2e, the 60e cluster opens one edge, as manifested in the butterfly motif. ==References== 〔 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「Butterfly cluster compound」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.
