Abstract
Two new compounds, [Zn(phen)3]2[γ-As8V14O42(H2O)] · 4H2O (1) and [Cd(phen)3]2[γ-As8V14O42(H2O)] · 2H2O (2) (phen = 1,10′-phenanthroline), have been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction, infrared spectrum, and thermogravimetric analysis. Compound 1 crystallizes in the triclinic space group P 1 with a = 11.429(4) Å, b = 15.760(5) Å, c = 15.952(5) Å, α = 108.825(5)°, β = 92.194(5)°, γ = 104.155(5)°, V = 2615.6(15) Å3, Z = 1; 2 crystallizes in the triclinic space group P 1 with a = 11.450(4) Å, b = 15.629(6) Å, c = 16.302(6) Å, α = 109.177(5)°, β = 92.628(5)°, γ = 104.251(4)°, V = 2644.8(17) Å3, Z = 1. Single-crystal structural analysis shows that both 1 and 2 consist of a new type of [γ-As8V14O42(H2O)]4− cluster anion.
