| 摘 要： | 1 INTRODUCTION Polyoxometallates are of great interest not only for their structural variety but also for their un- expected properties1, 2]. These inorganic anions had been widely investigated in catalysis, biology, me- dicine, magnetochemistry and materials science3～6]. Especially, the studies on the organic ligands coor- dinated by polyoxometallates might help to under- stand the catalytic mechanism of polyoxometallates. In recent years, several octamolybdates containing organic l…

Synthesis and Crystal Structure of a New Imidazole Coordinated Octamolybdate Compound |

| Abstract: | The title compound (Himi)4Mo8O26(imi)2]4H2O (imi = imidazole) 1 was synthe- sized by the reaction of H2MoO4 and imidazole in aqueous solution. Single-crystal X-ray analysis reveals that compound 1 is crystallized in the triclinic system, space group P with a = 10.6219(8), b = 10.7260(8), c = 11.3220(9) , a = 92.842(2), b =117.364(1), g = 101.655(1), C18H36Mo8N12- O30, Mr = 1668.11, V = 1106.8(2) 3, Z = 1, Dc = 2.503 g/cm3, F(000) = 804, m = 2.298 mm-1, the final R = 0.0714 and wR = 0.1651 for 3121 observed reflections with I > 2s(I). The X-ray crystal structure analysis suggests that compound 1 is built up by two imidazole ligands coordinated by the centrosymmetric octamolybdate anions, protonated imidazole cations and crystallization water molecules. |
