Paramolybdate

Japanese: パラモリブデン酸塩 - ぱらもりぶでんさんえん(英語表記)paramolybdate
Paramolybdate
A type of molybdate. Heptamolybdate is a common name for M I 6 [Mo 7 O 24 ]・ n H 2 O (7MoO 3 ・3M I 2 O・ n H 2 O). It is the most easily obtained of the polymolybdates, and is often what is called molybdate in analytical reagents. There is a heptapolyacid ion [Mo 7 O 24 ] 6-, which is a heptanuclear complex that shares the edges of an octahedral MoO 6 (Figure). It is generally obtained as a colorless crystal by adding an alkali hydroxide to an aqueous solution of molybdenum oxide (VI) MoO 3 and heating it; it is soluble in water.
