Many high-dimensional coordination complexes have been designed and prepared through molecular self-assembly processes. The open metal organic framework can be produced via two kinds of interactions, i. e. , coordinate covalent bonds and weaker intermolecular forces. For this reason, the most efficient means to synthesize these compounds is to establish possible connections among different units.展开更多

The compound crystallizes in monoclinic, space group P21/c with a = 10.837（2）, b = 16.551（3）, c = 23.402（5） A, p = 97.531（4）°, V = 4161.0（15） A3, Z = 4, Dc = 1.269 g/cm^3, F（000） = 1668, p = 0.414 mm^-1, R = 0.0479 and wR = 0.1232. The building unit of the title compound consists of three （phCH2N＋C5H5） ions, one [Fe（CN）6]^3- anion and four water molecules. According to the structural analysis, UFe（CN）6]^3- are linked together by O-H…N and O-H…O hydrogen bonds, but UFe（CN）6]^3- and [ （phCH2N＋ C5H5）3] ions are bound by electrostatic force to form an ionic compound.展开更多
