“…1. Compound 3 was prepared by minor modifications to the methodology reported by Besenyei et al (2013). The 4, 5, 6 and 7 organotin(IV) heterocycles were prepared according to the approach reported by Garcı ´a-Gonza ´lez et al (2024), by the reaction of precursor 3 with an excess of magnesium turnings and the corresponding diorganodihalogenstannane(IV) (R 2 SnX 2 ; X = Cl and Br) as limiting reagent in anhydrous tetrahydrofuran (THF).…”

A series of organotin heterocycles of general formula [{Me2C(C6H3CH2)2O}SnR 2] [R = methyl (Me, 4), n-butyl (n-Bu, 5), benzyl (Bn, 6) and phenyl (Ph, 7)] was easily synthesized by a Barbier-type reaction assisted by the sonochemical activation of metallic magnesium. The 119Sn{1H} NMR data for all four compounds confirm the presence of a central Sn atom in a four-coordinated environment in solution. Single-crystal X-ray diffraction studies for 17,17-dimethyl-7,7-diphenyl-15-oxa-7-stannatetracyclo[11.3.1.05,16.09,14]heptadeca-1,3,5(16),9(14),10,12-hexaene, [Sn(C6H5)2(C17H16O)], 7, at 100 and 295 K confirmed the formation of a mononuclear eight-membered heterocycle, with a conformation depicted as boat–chair, resulting in a weak Sn...O interaction. The Sn and O atoms are surrounded by hydrophobic C—H bonds. A Hirshfeld surface analysis of 7 showed that the eight-membered heterocycles are linked by weak C—H...π, π–π and H...H noncovalent interactions. The pairwise interaction energies showed that the cohesion between the heterocycles are mainly due to dispersion forces.

“…Compound [Au{X(PC) 2 }Cl)], with the analogous to xantphos diphoshane X(PC) 2 , is not emissive in dichloromethane solution, but in the solid state displays an structured blue-green emission, red shifted compared to that of the free diphosphane. [48]…”

Trigonal planar coordination at gold allows phosphorescent 3 MC transitions, not expected for luminescent mononuclear linear gold complexes. The careful selection and nature of the ancillary ligands bonded to gold, being fluorophore groups or not emissive ligands may cause a distortion of ideal trigonal planar coordination favoring different origins for the emissions. Consequently, intraligand (IL) or charge transfer (CT) transitions may be present and besides the expected phosphorescent MC transitions, fluorescence or thermally activated delayed fluorescence (TADF) may be the origin of the luminescence. In addition of the advantages of triplet population and deactivation via phosphorescent or delayed fluorescence processes, these systems are very versatile and may show interesting properties such as mechanochromism and vapochromism and, consequently, have revealed as promising candidates for optical applications. The objective of this review is to provide an overview of the reported luminescent three-coordinated gold systems and to get insight into their emissive properties.
