Abstract: | A new metal‐oxo cluster supported transition metal complex, Cu(en)2(H2O)]2Cu(en)2]0.5MoVI8VIV6VVO42{Cu(en)2}], has been synthesized under hydrothermal conditions. Its structure was determined by single‐crystal X‐ray diffraction. The compound crystallizes in the triclinic system, space group (No. 2), a = 12.245(5), b = 12.669(5), c = 20.949(8) Å, α = 77.120(13), β = 78.107(17), γ = 65.560(14)°, V = 2860(2) Å3, Z = 2. The metal‐oxo cluster contains a novel bicapped a‐Keggin structure unit and a Cu(en)2]2+ unit covalently bonded to the Mo8V7O42]7? cluster. |
