| Abstract: | The title complex Na (DB_18C_6) (H_2O)_2]_2Mo_6O_19·3DMF · 2CH_3OH (Ⅰ) , a new type of crown hexamolybdate supermolecule, has been synthesized. Its crystal structure has been determined by X-ray diffraction analysis. The crystal C_49H_32 Mo_6N_2Na_2O_40 is tetragonal, space group P4/mbm, a= 17.108(2), c= 28. 285 (6) A ,V=8279(2) A￣ 3, Z=4 , M_r= 1960. 8 , D_x=1. 573 g/cm￣3 , P=9. 51cm￣(-1). F(000)=3936. The final agreement factors R=0. 058 and R_w= 0. 062 for 1777 independent reflections with F>4σ(F). In contrast to what we have reported about Na(DB_18C_6)(CH_3OH)]_2Mo_6O_19(Ⅱ) where the whole complex was linked together, the cation Na (DB_18C_6 ) (H_2O)_2]￣ + , that has crystallographic D_2h symmetry, combines with the anion with the symmetry O_h by electronic interaction. |
