钼的混合配体络合物Mo(NO)(α-C_(10)H_(7)CS_(2))_(3)·1/2C_(4)H_(8)O_(2)的合成与结构

The Synthesis and Crystal Structure of a Heptaco ordinated Molybdenum Complex,Mo(NO)(α-C_(10)H_(7)CS_(2))_(3)·1/2C_(4)H_(8)O_(2)

采用简便方法引入亚硝基,合成了钼的三(α-萘荒酸基)单亚硝基混合配体络合物Mo(NO)(α-C_(10)H_(7),CS_(2))_(3)·1/2C_(4)H_(8)O_(2)。用X射线单晶衍射法测定了晶体结构。

Using a simple and convenient method,we have prepared the mononitrosyl compound Mo(NO)(α-C_(10)H_(7)CS_(2))_(3)·1/2C_(4)H_(8)O_(2).The crystal structure of this compound has been determined by the singlecrystal X-ray diffraction method.The crystal belongs to monoclinic space group C_(2h)^(5)-P2_(1)/a with unit cell parameters a=14.198(6)A.b=12.844(5)A,c=18.205(8)A,β=101.34(3)°,V=3254.9A^(3) and Z=4.The structure was refined to R=0.0947 for 3356 reflections.The coordination number for the Mo atom is seven.The coordination polyhedron around the Mo atom is semewhat distorted pentagonal bipyramid.The linear group of Mo-N-O occupies an axial position.Three α-dithionaphthoate ligands coordinate to Mo atom through the S atoms.
