Abstract
A novel title complex, C23H19N2O19Na4Y (Mr= 808.27), has been synthesized by hydrothermal reaction and structurally characterized by X-ray diffraction. It crystallizes in monoclinic, space group P21/n with a = 13.560(3), b = 14.016(3), c = 14.948(4) (A), β = 99.492(4)°, Z = 4,V= 2802.2(12) (A)3, Dc = 1.916 g/cm3, μ(MoKα) = 2.241 mm-1, F(000) = 1624, the final R = 0.0337and wR = 0.0828 for 4044 observed reflections(I＞ 2σ(I)). In the crystal, each eight- coordinated Y(Ⅲ) atom is linked by carboxyl groups of BTC to form a one-dimensional helical network structure.
