(C 14 N 14 H 63 ) Na (H 2 Mo 6 P 4 O 31 ) 2 · 8H 2 O (1) with amine‐separated sodium molybdenumphosphate clusters and (C 14 N 14 H 63 ) Na (H 2 Mo 6 P 4 O 31 ) 2 · 5H 2 O (2) with H‐bonded duster layers were synthesized from hydrothermal systems. Compound 1 crystallizes in the triclinic space group P · with a = 1.27445 (2) nm, b = 1.37183 (3) nm, c = 1.41515 (3) nm, α = 100.497 (1)°, β = 109.064 (1)° and γ = 115.498 (1)°. Whereas compound 2 has a monoclinic space group P 2 1 /n with a = 1.3418 (5) nm, b = 2.7787 (12) nm, c = 2.0314 (10) nm and β = 96.571 (14)°. There exist protonated ethylenediamine cations and H 2 O molecules between adjacent dusters, connecting the dusters through H‐bonds.
