  摘要：

  摘要辐照四羰基三苯基膦铁（0）制备了[Fe（ch）（CO）2PPh3]（1）（ch =查尔酮）和[Fe（sba）（CO）2PPh3]（2）（sba =山梨酸）在ch或sba的存在下与苯形成络合物。通过红外光谱和31P NMR光谱对化合物进行表征。通过循环伏安法研究了它们的电化学行为，结果表明它们的氧化是通过一个以上的电化学步骤发生的，产生了游离的ch和sba，游离的PPh3和溶剂化的Fe（III）。观察到，sba配体更有效地促进了这些配合物中金属中心的稳定。确定了1和2的X射线晶体和分子结构; 结果表明，Fe原子采用扭曲的八面体配位几何结构，其中三个位点被ch或sba配体占据。

  The (sorbic acid)Fe(CO)2L complexes, with L = CO, P(OPh)3, PPh3 and PEt3, have been prepared by irradiating the corresponding Fe(CO)4L compounds in benzene in the presence of sorbic acid. The Mössbauer spectra are compatible with the structure of a tetragonal pyramid with the iron(0) atom located in the center of the base. The values of the isomer shift, δ, seem to indicate that dπ-Lπ★ back bonding

  Tricarbonylmetal pi-complexes of unsaturated organic ligands containing CO2H, OH, and NH2 substituents are used as FTIR-readable molecular probes of solution pH. Wavenumber shifts in the nu(sym)(CO) and nu(asym)(CO) bands in the FTIR spectra of the complexes [(eta(4)-CH3-CH=CHCH=CHC O2H)Fe(CO)(3)], [(eta(4)-CH3CH=CHCH=CHCO2H)Fe(CO)(2)(PPh(3))], [(eta(6)-(CH5)-H-6-CO2H)Cr(CO)(3)], [(eta(6)-o-C6H4(CO2H)(2))Cr(CO)(3)], [(eta(6)-C6H5NH2)Cr(CO)(3)], [(eta(6)-p-CH3C6H4OH)-Cr(CO)(3)], and [(eta(6)-p-CH3O2CC6H4OH)Cr(CO)(3)], resulting from deprotonation or protonation of the complexes, can be correlated with the pH of the solution, enabling straightforward spectroscopic readout of pH. It is shown that, by appropriate choice of pH-sensitive functional group, a complex can be selected to respond over a particular pH range and that the pH response can be fine-tuned by the presence of other substituents on the organic unit. The narrow bandwidths of the nu(CO) vibrational modes allow the simultaneous use of more than one such complex in a solution. This approach, which we term the use of ''dual-sensor'' systems, has several advantages over single sensors, and its potential in the analysis of multianalyte systems is described.
