Abstract

An improved preparation of the malondialdehydate (mda) salt Na(mda)(H₂O) is reported; also described are preparations of copper(II) and palladium(II) complexes of mda and its 2-phenylmalondialdehydate (2-Ph-mda) analog. Crystal structures of Na(mda)(H₂O), Cu(mda)₂, Cu(2-Ph-mda)₂, Pd(mda)₂, and Pd(2-Ph-mda)₂ are described, along with nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) data. Cu(mda)₂ and Pd(mda)₂ deposit metallic thin films at 130 °C under chemical vapor deposition (CVD) conditions. Mechanistic studies show that Cu(mda)₂ transforms to copper metal by means of a ligand fragmentation pathway that involves carbon–carbon bond scission reactions.

铜（II）和钯（II）二元丙二脱水配合物的合成、表征及热裂解研究

报道了丙二醛（mda）盐Na(mda)（H2O）的改进制备方法；还描述了铜（II）和钯（II）丙二醛配合物及其2-苯基丙二醛（2-Ph-mda）类似物的制备。描述了Na(mda)(H2O), Cu(mda)2, Cu(2- ph -mda)2, Pd(mda)2和Pd(2- ph -mda)2的晶体结构，以及核磁共振（NMR）和电子顺磁共振（EPR）数据。Cu(mda)2和Pd(mda)2在化学气相沉积（CVD）条件下在130℃下沉积金属薄膜。机理研究表明，Cu(mda)2通过碳-碳键断裂反应的配体断裂途径转化为金属铜。

期刊介绍： The journal Chemistry of Materials focuses on publishing original research at the intersection of materials science and chemistry. The studies published in the journal involve chemistry as a prominent component and explore topics such as the design, synthesis, characterization, processing, understanding, and application of functional or potentially functional materials. The journal covers various areas of interest, including inorganic and organic solid-state chemistry, nanomaterials, biomaterials, thin films and polymers, and composite/hybrid materials. The journal particularly seeks papers that highlight the creation or development of innovative materials with novel optical, electrical, magnetic, catalytic, or mechanical properties. It is essential that manuscripts on these topics have a primary focus on the chemistry of materials and represent a significant advancement compared to prior research. Before external reviews are sought, submitted manuscripts undergo a review process by a minimum of two editors to ensure their appropriateness for the journal and the presence of sufficient evidence of a significant advance that will be of broad interest to the materials chemistry community.
