A common name for a salt of heteropolyacid made from phosphorus and molybdenum. The correct name is molybdophosphate. Examples include M I 4 [P 2 Mo 12 O 41 ], M I 3 [PMo 12 O 40 ], and M I 6 [P 2 Mo 18 O 62 ]. [Dodecamolybdophosphate] The general formula is M I 3 [PMo 12 O 40 ]. The structure of [PMo 12 O 40 ] 3- is a polynuclear complex in which polyacids are coordinated with P as the central atom (Figure). When an aqueous solution of phosphoric acid and molybdic acid is boiled, the free acid extracted with ether is dissolved in water and concentrated in a vacuum sulfuric acid desiccator to obtain free acid crystals.

リンとモリブデンからつくられるヘテロポリ酸の塩の俗称。正しくはモリブドリン酸塩という。MI4[P2Mo12O41],MI3[PMo12O40],MI6[P2Mo18O62]などがある。 [ドデカモリブドリン酸塩dodecamolybdophosphate] 一般式MI3[PMo12O40]。[PMo12O40]3-の構造はPを中心原子としてポリ酸の配位した多核錯体である(図)。リン酸とモリブデン酸の水溶液を沸騰させ,エーテルで抽出した遊離酸を水に溶かし,真空硫酸デシケーター中で濃縮すると遊離酸結晶が得られる。 出典 株式会社平凡社世界大百科事典 第2版について 情報 |
