The hydrothermal reaction of CuBr2 and tpyprz in the presence of NH4VO3 and HF for 72 h at 170°C provided [(tpyprz)3Cu10Br10] (1) in 20% yield. The two-dimensional structure of 1 may be described as Cu(I)-tpyprz chains, linked through {Cu4Br5}- clusters in the ac-plane and decorated with {Cu3Br5}2- clusters projecting from one face of the layer in the b-direction. The Cu(I) sites exhibit distorted trigonal coordination {CuBr3} and distorted tetrahedral geometries, {CuBr2N2} and {CuN4}. Crystal data for 1: monoclinic space group C2, a = 12.7561(8) Å, b = 19.359(1) Å, c = 15.860(1) Å, β = 97.178(1)°, V = 3885.8(4) Å3, Z = 2, Dcalc = 2.222 g cm-3, μ(Mo Kα) = 78.75 cm-1.
