Na3P is a source of the highly reactive phosphide anion. It should not be confused with sodium phosphate, Na3PO4. In addition to Na3P, five other binary compositions of sodium and phosphorus are known: NaP, Na3P7, Na3P11, NaP7, and NaP15.〔''Inorganic Chemistry'', Egon Wiberg, Arnold Frederick Holleman Elsevier 2001 ISBN 0-12-352651-5〕 ==Properties== Like K3P, solid Na3P features pentacoordinate P centers.〔 In the gas phase, molecular Na3P and Li3P are both trigonal pyramidal, with a lone pair of electrons on the central phosphorus atom. 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「Sodium phosphide」の詳細全文を読む スポンサード リンク
