| 摘 要： | 1 INTRODUCTION In the last decade, there has been great interest in the crystal engineering of supramolecular architectures organized by coordinate covalent bonds, hydrogen bonds and their combination owing to their fascinating structural diversity and potential applications as functional materials1~3]. The self-assembly of coordinate polymers and supramolecules is highly influenced by factors such as ligands, metal ions, the counter ions, solvent, template, reaction temperature, pH va…

Synthesis and Crystal Structure of a Seven-coordinate Cadmium(Ⅱ) Complex |

| Abstract: | The reaction of 4-hydroxybenzoic acid (H2L),4, 4-diaminodiphenylmethane (DADPM) and Cd(NO3)2?H2O in methane/water gave rise to a seven-coordinate Cd(Ⅱ) complex Cd2(HL)4(H2O)6]?H2O which has been characterized by single-crystal X-ray diffraction. The complex crystallizes in the orthorhombic system, space group Pna21 with unit cell parameters: a = 10.3352(3), b = 12.0481(3), c = 28.2016(1) ? V = 3511.65(13) 3, Z = 4, C28H36Cd2O20, Mr = 917.37, Dc = 1.735 g/cm3, F(000) = 1840, (MoK? = 1.29mm-1. The final R and wR are 0.0536 and 0.1086 for 4898 observed reflections with I ≥ 4(I). The Cd(Ⅱ) is seven-coordinated in a distorted pentagonal bipyramidal geometry. The inter-molecular hydrogen bonds lead to the formation of a two-dimensional layer structure. |
