The title compound was crystallized in the trigonal system, space group R3 with a=15.950 (3) Å, b=15.950 (3) Å, c=12.447 (2) Å, γ = 120°, V=2742.3 (9) Å3, Z=3, R1=0.031 and wR2=0.088. Left-handed and right-handed [MnMo9O32]6− polyanions enantiomers can be observed in compound (1). The homochiral enantiomers are consolidated by many hydrogen bonds involving ammonium cations and water molecules which are stacked into a 3D framework.
