摘要

(C14N14H63)Na(H2Mo6P4O31)2@8H2O (1) with amine-separated sodikum molybdebynogisogate clusters and (C14N14H63)Na(H2Mo6P4O31)2@5H2O (2) with H-bonded cluster layers were synthesized from hydrothermal systems. Compound 1 crystallizes in the triclinic space group P1 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 P21/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 H2O molecules between adjacent clusters, connecting the clusters through H-bonds.
