摘      要：The title complex crystallizes in the triclinic system, space group P1 with a=16.9568(5), b=18.8631(6), c=24.1640(8), α=100.110(1), β=92\^330(1), γ=113.368(1)°, V=7602.54(4)~3, D_c=3.002 g/cm^3, F(000)=5893, M_r=6245.25, μ(Mo Kα)=5.010mm^-1, Z=2 and final R=0.0722 and wR=0\^1960 for 16015 observed reflections with I≥2σ(I). The Gd(Ⅲ) ion is coordinated by nine oxygen atoms, forming a distorted mono-capped square antiprism, while the Mo(Ⅵ) ions have their different coordination numbers such as 4,5 and 6 with different configurations such as tetrahedron, square pyramid and octahedron, respectively.
