Abstract

The structure of Na₅[Cu{TeO₄(OH)₂}₂]·16H ₂O has been determined by X-ray structure analysis. It crystallises in the triclinic space group P1 with a = 5.922(4), b = 8.939(2), c = 12.528(2) Å, α = 98.45(1), β = 99.11(3), γ = 93.82(4)°, and Z = 1. The structure was refined to R = 0.040 for 2 131 observed reflections [F > 3σ(F)]. The composition of the crystal examined was deficient in sodium leading to a proposed formula Na_5-xH_x[Cu{TeO₄(OH)₂} ₂]·16H₂O (x = 0.64). The discrete centrosymmetric anion contains Cu^III with approximately square-planar CuO₄ groups linked by trans edges to TeO₄(OH)₂ octahedra [Cu-O 1.833(4) and 1.839(4) Å]. The [M{TeO₄(OH)₂}₂]^5- ions (M = Cu, Ag, or Au) have been studied by i.r., u.v.-visible, and n.m.r. (¹²⁵Te, ¹⁰⁹Ag, and ¹⁷O) spectroscopy. For [Ag{TeO₄(OH)₂}₂]^5- the ¹²⁵Te n.m.r. signal (+774 p.p.m.) is a doublet [²J(^107,109Ag-¹²⁵Te) = 73 Hz]. For the silver(III) ions [Ag{TeO₄(OH)₂}₂]^5- and [Ag{IO₅(OH)}₂]^5- the ¹⁰⁹Ag n.m.r. signals occur at ca. +2 800 p.p.m. from Ag⁺ (aq).
