摘要
A series of orizanogermanium(W) complexes with 2,5-dimercapto-4-phenyl-1,3,4-thiodiazole of the type, RnGe[S(C8H5N2S2)](4-n) (n = 3: R = CH3, 1: C2H5 2; C4H9, 3; C6H5, 4; n = 2, R = CH3, 5; C2H5, 6; C4H9, 7; C6H5, 8) have been synthesized. All the complexes 1-8 have been characterized by elemental, IR and H-1 NMR analyses. Among them complexes 4 and 8 have also been characterized by X-ray crystallography diffraction analyses, which revealed that the structure of complex 4 is a tetrahedron while the germanium environment of complex 8 is a distorted octahedron. Furthermore, an intermolecular non-bonded sulfur-sulfur interaction was recognized in complex 8. The IR and H-1 NMR spectral data indicate such an inclination that those structures of trialkylgermanium derivatives are apt to be four-coordinated and those of dialkylgermanium derivatives are likely to be six-coordinated.
