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.

挥发性杂金属：Pd–Pbβ-二酮的结构多样性及其与热学性质的关系

基于六氟乙酰丙酮铅（II）和主体Pd（II）的挥发性异双金属化合物已经研究了在β-二酮酸酯配体中同时包含各种供体原子和末端取代基的配合物，以追踪初始单金属配合物的性质对异双金属化合物的结构，组成和热性能的影响。异双金属化合物的结构变化和化学计量是由构成单金属部分之间竞争性供体-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，形成具有特定拓扑的多核结构。化合物的结构基序（离散或聚合）在很大程度上取决于最初的单金属配合物的结构和组成。
