The complexes are simple and inexpensive to synthesize, possess high volatility (vapor pressure = 0.1 Torr at 40 °C), and enable rapid deposition rates of nickel under CVD conditions (up to 6.5 nm/min at 250 °C). We show that the deposited nickel films have high elemental purity (>99 at%), resistivity comparable to bulk nickel (7-23 μΩ·cm cf. 6.93 μΩ·cm), exhibit shallow surface features (ca. ± 10 nm), and very low surface roughness (RMS = 2.72 nm). These data compare favorably with those of the current state-of-the-art metallic nickel CVD precursors.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"69 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144521439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report a new 2D layered halide double perovskite material, (BrPA)4AgSbBr8 (BPAS), and its properties are compared with (BrPA)4AgInBr8 (BPAIn, PA─propylammonium) and previously reported noncentrosymmetric Cl0.26Br3.74PA4AgSbBr8 (CPAS, CPA─chloropropylammonium). BPAS and BPAIn crystallize in the P2/c monoclinic space group with 2D layers of inorganic octahedra formed by monovalent and trivalent cations separated by two layers of organic linkers. Unlike their 3D counterparts, Cs2Ag(In/Sb)X6 (X-halide), the octahedra are distorted, reducing their symmetry. This led to the broadening of the optical gap in the present materials and also affected the photoluminescence (PL) and conduction properties. The BPAS shows a slight indirect band gap but shows PL emission with contributions from band-to-band, free/bound excitonic, and self-trapped excitonic states. The STEs enabled broader emission in these two materials. The 2D nature of the material shows anisotropic conduction properties where the in-plane conduction is found to be different from out-of-plane conduction. The value of charge transfer resistance decreases from GΩ (at -73 °C) to kΩ (at 202 °C) due to the presence of thermally activated carrier mobility through a correlated barrier hopping mechanism.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"27 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144521505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photodissociation of trans(Cl,Cl)-[Ru(bpy)(CO)2Cl2] yielded two monocarbonyl complexes, cis(Cl,Cl),trans(Cl,CH3CN)-[Ru(bpy)(CO)(CH3CN)Cl2] and trans(Cl,Cl)-[Ru(bpy)(CO)(CH3CN)Cl2], as the major and minor stereoisomeric products, respectively. The apparent quantum yields for the second CO dissociations were 0.56% and 0.78% for cis(Cl,Cl),trans(Cl,CH3CN)- and trans(Cl,Cl)-isomers, respectively. Considering the efficient photoisomerization of the trans(Cl,Cl)- to cis(Cl,Cl),trans(Cl,CH3CN)-isomer, the trans(Cl,Cl)-isomer would have a higher quantum yield. We also isolated the monocarbonyl complex after the first CO dissociation of trans(Cl,Cl)-[Ru(6Mes-bpy)(CO)2Cl2] (6Mes-bpy = 6,6'-dimesityl-2,2'-bipyridine), which contains bulky substituents at the 6,6'-positions of the bpy ligand. X-ray crystal structure analysis revealed the selective formation of trans(Cl,Cl)-[Ru(6Mes-bpy)(CO)(CH3CN)Cl2]. The quantum yield for the second CO dissociation from this structure was found to be 2.0%, nearly four times larger than that of cis(Cl,Cl),trans(Cl,CH3CN)-[Ru(bpy)(CO)(CH3CN)Cl2]. Time-resolved IR (TRIR) measurements demonstrated that photoirradiation of cis(Cl,Cl),trans(Cl,CH3CN)-[Ru(bpy)(CO)(CH3CN)Cl2] produced a five-coordinate pyramidal square intermediate with a stronger Ru-CO bond than in the ground state. In contrast, no such intermediate was observed for trans(Cl,Cl)-[Ru(6Mes-bpy)(CO)(CH3CN)Cl2]. The presence of this intermediate is thought to be a key factor in inhibiting further CO dissociation.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"19 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144521447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
