  An oxide chain constructed from octamolybdate, a Keggin anion and a copper (II) – Tetrapyridylpyrazine binuclear unit

  摘要：

  The hydrothermal reaction of MoO3, CuSO4 center dot 5H(2)O, tetra-4-pyridylpyrazine (tpyprz). and diphenyidiarsonic acid in water at 140 degrees C for 48 h yielded the one-dimensional material [{Cu-2(tpyprz)(H2O)(3)}(2){Mo8O26} (Mo12O36(AsO4)}]center dot 8H(2)O (1 center dot H2O). The chain structure of 1 center dot 8H(2)O is constructed from alternating beta-octamolybdate clusters and molybdoarsonate Keggin clusters linked through {Cu-2(tpyprz)(H2O)(3)}(4+) binuclear subunits. The Cu(II) sites are inequivalent with one copper bonding to two pyridyl donors and a pyrazine nitrogen of one terminus of the tpyprz ligand, two aqua ligands and an oxo-group of the beta - Mo8O264- cluster while the second copper site coordinates to the nitrogen donors of the other terminus of the tpyprz ligand, an aqua group, a terminal oxo-group of the beta - Mo8O264- cluster and a terminal oxo-group of the mixed valence {(Mo11MoO36)-Mo-VI-O-V(AsO4)}(4-) Cluster. Crystal data: C48H60AsCu4Mo20N12O80: FW = 4332.96 Tri-clinic P (1) over bar, a = 12.5087(5) angstrom, b = 13.6681(6) angstrom, c = 14.8980(6) angstrom. alpha = 92.196(1)degrees, beta = 97.046(1)degrees, gamma = 97.751(1)degrees, Z = 1, D-calc = 2.877 g cm(-3); structure solution and refinement based on 12,333 reflections (Mo K-alpha, lambda = 0.71073 angstrom) converged at R-1 = 0.0540 and wR(2) = 0.1115.
