“…In literature, great efforts provide access to the nanoscale materials, ranging from inorganic metal clusters to custom-built single molecules [44]. Ternary metal complexes have played a significant role as precursors in the production of nanoparticles, using different techniques, such as thermal decomposition, UV irradiation, sonication, microwave, etc.…”

“…Ternary metal complexes have played a significant role as precursors in the production of nanoparticles, using different techniques, such as thermal decomposition, UV irradiation, sonication, microwave, etc. [44]. Nevertheless, literature has not afforded a clear example of the synthesis of nanoscale ternary complexes though there are a few that have alleged to have done so; however, the authors did not supply clear evidence to confirm the actual size and shape of their molecules.…”

A successful oligomerization of ternary metal complexes, cobalt (II), nickel (II), copper (II), zinc (II), chromium (III) and ferric sulfate (III) with nitrilotriacetic acid (NTA) as a primary ligand and glutamic acid as a secondary ligand, has been demonstrated. The formation of oligomers arose from the presence of the sulfate moiety, which operates as a bridged bidentate ligand that coordinates with other metal moieties. The novel oligomers exhibited octahedral structures, which bonded together through the sulfate moiety. In silico predictions were conducted to gauge the bioactivity, physico-chemical and pharmacokinetic properties. The biological activities of these oligomers as well as their tumor inhibitory behavior have been explored. This work also presents a facile and novel method of preparing these materials in nanosize, using Cetyltrimethylammonium bromide (CTAB) and polyvinyl alcohol (PVA) as capping ligands. The size and shape of the nanomaterials have been confirmed using the transmission electron microscope (TEM) and the scanning electron microscope (SEM).

“…The typical organic groups of the chalcogen atom are mostly used as methyl, ethyl, phenyl or trimethyl silyl groups. However, in few cases complexes containing both chalcogenolate and chalcogenide groups have been observed due to the elimination of organic group ,…”

The reactions of InCl3 with Na{Se(CH2)nNMe2} in 1:2 stoichiometry yielded complexes of composition [InCl{Se(CH2)nNMe2}2] (n=2 (1) or 3 (2)). Treatment of Me2InCl with Na(4‐SeC5H4N) afforded [Me2In(4‐SeC5H4N)]n (3). Copper complex [(PEt3)2Cu2(4‐SeC5H4N)2]n (4) was synthesized from CuCl, PEt3 and Na(4‐SeC5H4N). These complexes have been characterized by elemental analysis and NMR spectroscopy. Solid‐state structures of 3 and 4 revealed the formation of one‐ and two‐dimensional co‐ordination polymer which is formed via Se and N atoms of selenolate ligand. Thermal studies of these complexes have been carried out in a furnace or oleylamine to give thin film or nano‐materials of In2Se3, Cu1.8Se and CuInSe2.

“…4,5 New developments in the latter respect came from the utilization of small clusters as building blocks for the formation of nanoparticles with controllable size and shape through photolytic decomposition and solvothermal synthesis. [6][7][8][9][10] For some time metal chalcogenolato complexes have also been investigated due to oligomeric (e.g. ring-like) or polymeric structures.…”

Reactions of [Co(N(SiMe))thf] with 2.1 equiv. of MesSH (Mes = CH-2,4,6-(CH)) yield dark brown crystals of the one dimensional chain compound [Co(SMes)]. In contrast reactions of [Co(N(SiMe))thf] with 2.1 equiv. of PhSH result in the formation of a dark brown almost X-ray amorphous powder of 'Co(SPh)'. Addition of aliquots of CHOH to the latter reaction resulted in the almost quantitative formation of crystalline ammonia thiolato complexes either [Co(SPh)(NH)] or [Co(SPh)NH]. Single crystal XRD reveals that [Co(SPh)NH] forms one-dimensional chains in the crystal via μ-SPh bridges whereas [Co(SPh)(NH)] consists at a first glance of isolated distorted tetrahedral units. Magnetic measurements suggest strong antiferromagnetic coupling for the two chain compounds [Co(SMes)] (J = -38.6 cm) and [Co(SPh)NH] (J = -27.1 cm). Interestingly, also the temperature dependence of the susceptibility of tetrahedral [Co(SPh)(NH)] shows an antiferromagnetic transition at around 6 K. UV-Vis-NIR spectra display d-d bands in the NIR region between 500 and 2250 nm. Thermal gravimetric analysis of [Co(SPh)(NH)] and [Co(SPh)NH] reveals two well separated cleavage processes for NH and SPh upon heating accompanied by the stepwise formation of 'Co(SPh)' and cobalt sulfide.

Abstract: Ternary clusters Cu(9)In(10)S(9)(SEt)(21)(PPh(3))(3) and Cu(11)In(6)S(7)(S(t)Bu)(15) were isolated from the UV-photolysis products of precursors (PPh(3))(2)CuIn(SEt)(4) and (PPh(3))(2)CuIn(S(t)Bu)(4), respectively, and structurally characterized.
