The hydrothermal reaction of Cu(CH3CO2) 2•H2O, MoO3, tetrapyridylpyrazine (tpyprz), and 2-hydroxypropyl-1,3-diarsonic acid provided green crystals of the bimetallic oxide phase [{Cu2(tpyprz)(H2O)}Mo 6O18(H2O){O3AsCH2CH(OH) CH2AsO3}]•5.5H2O (1•5.5H 2O). The two-dimensional structure of 1•5.5H2O is constructed from {Mo6O18(H2O)(O 3AsR)2}n4n - chains linked through {Cu2(tpyprz)(H2O)}4+ rods into a network. The hexanuclear molybdate ring consists of a tetrad of edge-sharing {MoO 6} octahedra that adopt the corner-sharing mode to a diad of face-sharing Mo octahedra. Crystal data for C27H37As 2Cu2Mo6N6O32.5: monoclinic P21/c, fw = 1818.18, a = 13.1304(9) Å, b = 21.701(1) Å, c = 17.408(1) Å, β = 100.046(1)°, V = 4884.2(6) Å3, Z = 4, Dcalc = 2.472 g cm- 3, R1 = 0.0669.
