摘 要: | 1 INTRODUCTION The assembly of coordination networks is a field of increasing interest[1~4]. Research along this line is induced by the idea that coordination networks have potential technological applications such as optoele- ctronic devices and microporous materials for shape and size separation and catalysis[5~7]. In this paper, there has been current interest in using polycarboxy- late as anion linking groups to support stable poly- meric coordination open frameworks with transition m…

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 mono- clinic, space group P21/n with a = 13.560(3), b = 14.016(3), c = 14.948(4) ?, β = 99.492(4)o, Z = 4, V = 2802.2(12) ?3, Dc = 1.916 g/cm3, μ(MoKα) = 2.241 mm?1, F(000) = 1624, the final R = 0.0337 and 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. |
