SYNTHESIS AND STRUCTURE OF A MIXED-VALENCE HEXAMOLYBDENUM COMPLEX [Et_4N]_2[Mo_6O_(19)H_4]

【摘要】:正 A hexamolybdenum complex, [Et_4N]_2[Mo_6O_(19)H_4] crystal, withpentavalent and hexavalent molybdenum has been obtained in the solution ofDMF and CH_3OH as organic solvents using MoCl_5 as a starting material. Thecrystallographic parameters obtained by X-ray diffraction analysis are:crthorhombic, a=10. 757(3), b=10. 763(2), c=14. 238(4)A, =1648. 9A~3; Z=2; spacegroup Pnnm; final R=0. 047; final Rw=0. 051~(**)
