摘 要: | 1 INTRODUCTION Recently, much interest has been focused on various extended framework due to their intriguing architectures, new topologies and potential applications in microelectronics, nonlinear optics, molecular selection, ion exchange and catalysis1~4] . In the last few years, a wide range of infinite structures with diverse topologies has been prepared by the reaction of metal ions with mulriple organic ligands5~9]. However, up to now, much of the work has been concentrated on c…

Abstract: | A 3-D coordination polymer PbNH(CH2COO)2] 1 has been prepared under hydrothermal conditions and its crystal structure was studied by single-crystal X-ray diffraction. The compound belongs to orthorhombic system, space group Fdd2 with unit cell parameters: a = 13.6304(6), b = 36.295(1), c = 5.0821(2) ? V = 2514.19(17) 3, Z = 16, Mr = 338.28, Dc = 3.575 g/cm3, F(000) = 2400 and m(MoKa) = 2.679 cm-1. The final R and wR are 0.0290 and 0.0685, respectively, for 874 observed reflections with I > 2s(I). The lead has a distorted tetragonal pyramid environment with four oxygen donors in the basal plane and one nitrogen donor in the axial site. Micro-channels are observed in the neutral 3-D network of 1. |
