  名称：

  Crystal structure of [NBun4]2[Nb(C3S5)2(S2)2Nb(C3S5)2] (C3S52−=4,5-disulfanyl-1,3-dithiole-2-thionate) and dissociation behavior in solution

  摘要：

  The crystal structure of [NBu4n](2)[Nb(C3S5)(2)(S-2)(2)Nb(C3S5)(2)] (C3S52- = 4,5-disulfanyl-1,3-dithiole-2-thionate(2-)) has been determined by X-ray analysis. The complex crystallizes in the monoclinic space group P2(1)/n (No. 14) with a=9.461(3), b=20.161(3), c = 18.129(1) Angstrom, beta=92.47(2)degrees and Z=2. The structure was refined to R (R-w) = 0.063 (0.101) using 2924 observed reflections with I-o> 3 sigma(I). The anion has a centrosymmetric binuclear structure. Each Nb(V) atom is coordinated by four sulfur atoms of two C3S52- ligands and four sulfur atoms of two S-2(2-) ligands forming a distorted octahedral geometry if each S-2(2-) ligand is considered to occupy a single coordination site. The intermolecular non-bonded S-S contacts (< 3.7 Angstrom) form a three-dimensional molecular interaction network among the anion moieties. The electrospray ionization mass spectrum of the complex dissolved in dichloromethane indicated the dissociation of the binuclear anion moiety into the [Nb(S-2)(C3S5)(2)](-) species in solution.
