摘要：

Crystals of Na16[Zn4(H2O)2(alpha-P2W15O56)2]. approximately 50H2O are triclinic, P1BAR, with a = 14.670(5), b = 14.661(5), c = 19.817(3)angstrom, alpha = 84.95(3), beta = 81.51(3), gamma = 65.73(3)degrees. Least-squares refinement converged at R = 0.053 for 5906 independent data with I > 3sigma(I). The centrosymmetric anion consists of two alpha-P2W15O56(12-) ligands attached to a planar group of four Zn2+, two of which also carry water molecules. The distortions in the ZnO6 octahedra and in the W15 framework of the ligands are smaller than the corresponding distortions in the otherwise similar [Cu4(H2O)2(P2W15O56)2]16- anion.
