TL;DR: In this article, the reactions of N,N′-bis(salicylidene)propane-1,3-diamine (salpropH2) and its substituted derivatives with Ga(acac)3 afforded the complexes [Ga(acAC)(salprop)]·0.5H2O (1), [Ga (acac)(5ClSalprop)] (2), [ga(ac ac)(5Rsalprop2− ligand and one bidentate chelate acac+ ligand), in high yields.

TL;DR: In this paper, a bimetallic complex Ba 2 Sn 2 (thd) 4 (O i Pr) 8 (i PrOH) 2 (1) was obtained with quantitative yield by interaction of Sn(O i pr) 4 with 1 1/eq. of Ba(thd)-2 produced in situ in toluene.

TL;DR: In this article, the tetrahedrally-shaped crystals of Zr(Bisacac)2 and Hf(BISACAC)2, M(IV) derivatives of bisacetylacetone (tetra-acetyl-ethane), were obtained in quantitative yield by a simple and reproducible synthetic procedure.

TL;DR: In this paper, modern approaches in the synthesis of metal alkoxides, with a special focus on molecular structure and reactivity, are summarized, and a brief but up-to-date presentation of the reaction mechanisms are given.
Abstract: This chapter summarizes modern approaches in the synthesis of metal alkoxides, provides an overview of their physical and chemical properties, with a special focus on molecular structure and reactivity, and gives a brief but up-to-date presentation of the reaction mechanisms in the synthesis of inorganic materials from metal alkoxides as precursors (alkoxosynthesis). A critical overview of molecular precursor approaches exploiting homo- and heteroleptic alkoxide complexes is provided, explaining the role of heteroligands in nucleation and subsequent growth of the resulting nanostructured materials. This chapter also provides a brief summary of other principal applications of metal alkoxides, such as homogeneous catalysts and molecular magnets, with a special focus on the synthesis and structure of these functional molecules.

TL;DR: In this article, a family of exceptionally thermally stable [Ni8] cages is reported, each being templated by a rare η3:η3-μ6-O22− species produced by dioxygen activation, where the reducing agent for the O2 reduction appears to be the ligand used in the reaction mixtures, which was found within the nickel cages in its oxidized form.

TL;DR: This review summarizes the major progress in the field, including the principles that permit atomically precise synthesis, new types of atomic structures, and unique physical and chemical properties ofatomically precise nanoparticles, as well as exciting opportunities for nanochemists to understand very fundamental science of colloidal nanoparticles.
Abstract: Colloidal nanoparticles are being intensely pursued in current nanoscience research. Nanochemists are often frustrated by the well-known fact that no two nanoparticles are the same, which precludes the deep understanding of many fundamental properties of colloidal nanoparticles in which the total structures (core plus surface) must be known. Therefore, controlling nanoparticles with atomic precision and solving their total structures have long been major dreams for nanochemists. Recently, these goals are partially fulfilled in the case of gold nanoparticles, at least in the ultrasmall size regime (1–3 nm in diameter, often called nanoclusters). This review summarizes the major progress in the field, including the principles that permit atomically precise synthesis, new types of atomic structures, and unique physical and chemical properties of atomically precise nanoparticles, as well as exciting opportunities for nanochemists to understand very fundamental science of colloidal nanoparticles (such as the s...
