摘要

Two novel sodium complexes NaBb (1) (Bb = dihydrobis(2-mercapto-benzimidazolyl)borate) and NaBt~(Me) (2) (Bt~(Me) = dihydrobis(2-mercapto-4-methylthiazolyl)borate) have been prepared and characterized by using two heterocycles, 2-mercapto-benzimidazole and 2-mercapto-4-methylthiazole, as well as NaBH_4 as precursors. The dipodal boron centred soft ligands Bb and Bt~(Me) were prepared in situ. The reactivity of NaBb (1) and NaBt~(Me) (2) towards Bi(III) ions has been studied. The resulting complex BiBb_2Cl (3) contains an MS_4 core with κ~3-S,S,H coordination mode, while the complex BiBt~(Me) 3 (4) with an MS6 core adopts a coordination mode κ2-S,S. A reaction of BiCl3 with the heterocyclic precursors 2-mercapto-benzimidazole (L~1) and 2-mercapto-4-methylthiazole (L~2) was also attempted; this afforded the monomeric BiL_4~1Cl_2BiL_2~1Cl_4 (5) and dimeric BiL_2~2(μ-Cl)Cl_2 (6) bismuth complexes. The bismuth complexes possess distorted octahedral geometries except 3 for which a face-capped octahedron is found. The presence of (B)H?Bi interactions has been identified by X-ray diffraction in 3 with a H?Bi distance of 2.58(1) ? which is uniquely short and unprecedented. Two of the synthesized complexes (4 and 5) have been investigated by luminescence spectroscopy. They feature emission bands in the solid state at room temperature at 674 (4) and 586 nm (5), which are hypsochromically shifted in (frozen) ethanolic solutions at 77 K to 618 and 537 nm, respectively.
