【Abstract】 QH)3[Mo2O4 (■)(NCS)4·H2O(Ⅰ) is crystallized in the rhombo- hedral system with space group P212121; the lattice parameters are a=11 .196 (8) b=16.558(8), c=21.867(8) A, d=1.65g/cm3, where by z= 4 ( dc= 1.651g/ cm3 >. But (QH3 )[Mo2O4(CH3OH)(NCS)5](Ⅱ) is crystallized in the triclinic system with space group P 1: the lattice parameters are a=10. 593(3). b=11. 266 (7), c=16 .795(9), α=102. 58(5), β=90.45(5), v= 95 .18(4), dm=1. 65g/cm3, z- 2, (dc=1 .652g/cm3 ). The structure has been solved by three-dimensional Patter- son and Fourier synthesis methods and refined by least squares procedures to a final R value 0.079 for structure (Ⅰ) and 0.080 for structure(Ⅱ) The configu- ration of clirster skeleton of (Ⅰ)and (Ⅱ) are similar to the other di-μ-O-brid- ged oxodimolybdates(Ⅴ) in which the coordination around each molybdenum atom are a distored octahedron sharing two bridged Ob atom. But the ligand coor- dinated to two molybdenum atoms are asymetric. The bridging oxygen atoms form Ob …H-N hydrogen bond with quinoliniuni cation in both crystal structurs (Ⅰ) and(Ⅱ).更多还原
