The chemistry of aroylhydrazines has been attracting attention mainly due to the residual functional group, –CONH–NH₂, which has important effects on hydrophilicity and has the potential to provide special interaction sites for targeting molecules. The reaction of a dipodal aroylhydrazine, typically isophthalohydrazide (isphz), with trans-[ReOX₃(PPh₃)₂] in acetone led to the isolation of ligand-bridged oxidorhenium(V) dinuclear complexes (μ-dphz)[ReOX₂(PPh₃)]₂, (X = Cl (1), Br (2). The novel dianion dipodal aroylhydrazone Schiff base N′¹,N′³-di(propan-2-ylidene)isophthalohydrazide (dphz²⁻) was formed by the condensation of acetone with isphz and coordinated to each of the [ReO]³⁺ units as a monoanionic N,O-donor chelate, bridging via the dphz²⁻ dianion. The reaction of a tripodal aroylhydrazine, typically benzene-1,3,5-tricarbohydrazide (bthz), with trans-[ReOBr₃(PPh₃)₂] in acetone led to the isolation of the ligand-bridged oxidorhenium(V) trinuclear complex (μ-tbhz)[ReOBr₂(PPh₃)]₃ (3). The novel trianion tripodal aroylhydrazone Schiff base N′¹,N′³,N′⁵-tri(propan-2-ylidene)benzene-1,3,5-tricarbohydrazide (tbhz³⁻) was also formed from the condensation of acetone with bthz and coordinated to each of the [ReO]³⁺ units as a monoanionic N,O-donor chelate, bridging via the tbhz³⁻ trianion. The crystal structures, infra-red (IR), ¹H-NMR, and ³¹P-NMR spectroscopy of the complexes are reported. In addition, the density functional theory (DFT) calculations and the chromatographic behavior of the synthesised complexes are studied.

氧化or（V）与二脚和三脚芳酰肼的反应：形成双核和三核芳酰hydr桥接的（（V）配合物

芳酰肼的化学性质一直受到关注，主要是由于残留的官能团–CONH–NH ₂，它对亲水性具有重要影响，并有可能为靶向分子提供特殊的相互作用位点。二足芳酰基肼，通常为间苯二甲酰肼（isphz）与反式-[ReOX ₃（PPh ₃）₂ ]在丙酮中的反应导致配体桥连氧化（V）双核配合物（μ-dphz）[ReOX ₂（ PPh ₃）] ₂，（X = Cl（1），Br（2）。新型二价二阴离子芳烃hydr席夫碱N' ¹，Ñ ' ³ -二（丙-2-亚基）isophthalohydrazide（dphz ^2-）通过用isphz丙酮的缩合形成，并且配位到每一个[REO]的³⁺单元作为单阴离子N，O供体螯合，通过dphz ^2-双阴离子桥接。三脚架芳酰基肼（通常为苯-1,3,5-三碳酰肼（bthz））与反式-[ReOBr ₃（PPh ₃）₂ ]在丙酮中的反应导致分离配体桥连的氧化hen（V）三核配合物（μ-tbhz）[ReOBr ₂（PPh ₃）] ₃（3）。该新型三价阴离子三足aroylhydrazone席夫碱Ñ ' ¹，Ñ ' ³，Ñ ' ⁵ -三（丙-2-亚基）苯-1,3,5- tricarbohydrazide（tbhz ^3-）也从丙酮与缩合形成bthz与每个[ReO] ³⁺单元配位，为单阴离子N，O-给体螯合物，通过tbhz ^3-三阴离子桥接。晶体结构，红外（IR），¹ H-NMR和³¹报道了配合物的P-NMR光谱。此外，还研究了密度泛函理论（DFT）的计算和合成配合物的色谱行为。
