The crystal structure of hexaammonium diacetyl‐octa‐molybdate tetrahydrate, (NH 4 ) 42 [Mo 132 O 372 (CH 3 COO) 30 (H 2 O) 72 ] is documented. The crystals are triclinic, space group P‐1, with a=8.1018(16) Å, b=10.334(2) Å, c=12.238(2) Å, α=68.20(3)°, β=74.98(3)°, γ=67.25(3)°, V=869.3(3) Å 3 , Z=1. The structure was solved by direct methods and refined by least squares methods to a Final R1 = 0.0374 and wR2 = 0.1074 for 3805 observed reflections with I > 2σ(I). The structure contains ammonium cations and isolated acetyl octamolybdate(6‐) anions, [Mo 8 O 28 (CH 3 CO) 2 ] 6‐ . The crystallographic data of the structure was deposited with the Cambridge Data Center as No. CCDC 249565. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
