NEt(4)[Re(CO)(3)Br(3)] reacts with 2-acetylpyridine phenylthiosemicarbazone (HL(1)) and 2-pyridine formamide thiosemicarbazone (HL(2)) under formation of air-stable, neutral rhenium(I) complexes of the compositions [Re(CO)(3)(L(1)-N,N,S)] and [Re(CO)(3)Br(HL(2)-N,N)]. Spectroscopic studies and X-ray crystallography show that the potentially tridentate thiosemicarbazones adopt unusual coordination modes. Whereas HL(1) deprotonates and binds to the metal in a nonplanar fashion, HL(2) acts as neutral N,N donor ligand. The bond lengths inside the chelate rings are almost uninfluenced by the overall bonding situation.
[四乙基铵]₂[三溴三羰基铼(I)]与2-乙酰基吡啶苯硫代氨基脲（HL¹）和2-吡啶甲酰胺硫代氨基脲（HL²）反应，生成了组成分别为[三羰基铼(I)(L¹-N,N,S)]和[三溴三羰基铼(I)(HL²-N,N)]的空气稳定的中性铼(I)配合物。光谱研究和X射线晶体学表明，潜在的三齿硫代氨基脲采用了不寻常的配位模式。HL¹去质子化并以非平面方式与金属结合，而HL²作为中性的N,N供体配体。螯合环内的键长几乎不受整体键合情况的影响。
