以六氟乙酰丙酮酸铅（Pb（ii））为主体材料，研究了一系列β-二酮配体中同时含有不同给体原子和末端取代基的Pd（ii）配合物，考察了初始单金属配合物的性质对杂双金属化合物的结构、组成和热性能的影响.杂环化合物的结构多样性和化学计量是由构成单体部分之间的竞争性供体-受体相互作用的各种组合引起的。主要的结构形成因素是Pd和Pb原子之间的亲金属相互作用，导致具有特定拓扑结构的多核结构。化合物的结构基序（离散的或聚合的）显著地取决于初始单核苷酸络合物的结构和组成。提出了利用结构数据和量子化学计算结果解释和预测这些化合物热稳定性的方法。
Volatile heterobimetallics based on Pb(ii) hexafluoroacetylacetonate as a host material and a range of Pd(ii) complexes containing both various donor atoms and terminal substituents in the β-diketonate ligand have been studied to trace the influence of the nature of the initial monometallic complexes on the structure, composition and thermal properties of heterobimetallic compounds. The structural variety and stoichiometry of the heterobimetallic compounds are caused by various combinations of the competing donor-acceptor interactions between the constituting monometallic moieties. The major structure forming factor is the metallophilic interaction between Pd and Pb atoms resulting in polynuclear structures with a specific topology. The structural motif (discrete or polymeric) for the compounds significantly depends on the structure and composition of the initial monometallic complexes. The approach for explaining and predicting the thermal stability of these compounds is proposed by using their structural data and the results of quantum chemistry calculations.
