Bjs. Johnson et al., Tetrakis(tetrabutylammonium)tetrakis[(p-cyanophenyl)trioxoarsonato]tetratriacontaoxododecamolybdate(4-), ACT CRYST C, 55, 1999, pp. 549-551
Crystals of the title compound, (C16H36N)(4)[(p-NC-C6H4As)(4)Mo12O46] or (C
16H36N)(4)[{As(C7H4N)}(4)Mo12O46], were synthesized by the reaction of p-cy
anophenylarsonic acid and sodium molybdate at low pH. With nitrile groups p
ointed in tetrahedral directions, these new organically modified polyoxomet
alate clusters are potential building blocks in coordination networks.
