In this report, the 59Tc labelling of Annexin V fragment modified with HYNIC (HYNIC-Anx13) using Tricine, EDDA or EDDA/Tricine as coligands was described. The effect of various factors on 99Tc labelling was investigated. Biodistribution studies in normal mice and gamma imaging of apoptosis in rats induced by cyclophosphamide were performed.

Solid complexes of rare earth picrates with the ligand 2,6-bis(benzimidazol-2-yl)pyridine have been synthesized and characterized by elemental analysis, IR and electronic spectra. The crystal and molecular structures of the complex [CeL22]·(CH3OH)3 have been determined by single crystal X-ray diffraction.

合成了稀土苦味酸盐与配体2，6-二(2-苯并咪唑基)吡啶的配合物，通过元素分析、红外光谱及电子光谱对配体及配合物进行了表征，并用X射线单晶衍射测定了配合物[CeL22]·(CH3OH)3的晶体结构。

The coordinated COD of 3 and 4 can be replaced by carbon monoxide to yield the corresponding dicarbonyl species [(C,N-pyN^C-R) M2]BF4 (14, M= Rh; 15, M= Ir). Ligand substitution of 11a by phosphines and azide causes the de-complexation of pyridinyl-nitrogen donor to generate the corresponding carbene rhodium complexes [(C-pyN^C-Mes)RhPR3] (17a, R = Ph, 17b, R = Et) and [RhN3] (19), respectively, indicating the labile nature of steric-hindered pyridinyl-nitrogen donor.

螯合错合物的吡啶配位，可以容易被σ-予体，如卤离子、叠氮阴离子、膦试剂，置换；但是铑与铱金属螫合物与π-酸试剂，如一氧化碳、异腈，则发生COD被置的产物14a与16；与三甲基亚磷酸酯反应时，COD及吡啶均会被取代而得到单芽的三铑-碳烯错合物18；双膦化合物则会取代铑金属上全部的配位基。
